00:00:10,230 --> 00:00:07,990
hi good afternoon i'm rob gutrow from

2
00:00:11,830 --> 00:00:10,240
nasa's goddard space flight center

3
00:00:13,669 --> 00:00:11,840
in the office of communications also

4
00:00:16,790 --> 00:00:13,679
manager of the nasa hurricane page we're

5
00:00:19,590 --> 00:00:16,800
here today for uh an hs3 google hangout

6
00:00:21,029 --> 00:00:19,600
hs3 means hurricane and severe storm

7
00:00:23,029 --> 00:00:21,039
sentinel

8
00:00:25,429 --> 00:00:23,039
google hangout

9
00:00:27,589 --> 00:00:25,439
the hs3 mission is a five year mission

10
00:00:29,269 --> 00:00:27,599
this is the second year of the mission

11
00:00:30,390 --> 00:00:29,279
and we'll be finding out what's brand

12
00:00:32,709 --> 00:00:30,400
new for this year

13
00:00:35,910 --> 00:00:32,719
with our four panelists

14
00:00:37,670 --> 00:00:35,920
just a little bit about the hs3 mission

15
00:00:39,350 --> 00:00:37,680
the hs3 mission

16
00:00:41,430 --> 00:00:39,360
purpose is to

17
00:00:43,590 --> 00:00:41,440
investigate the processes that underlie

18
00:00:45,430 --> 00:00:43,600
hurricane formation and the intensity

19
00:00:48,069 --> 00:00:45,440
changes of tropical cyclones in the

20
00:00:50,790 --> 00:00:48,079
atlantic ocean among those factors hs3

21
00:00:54,310 --> 00:00:50,800
will address the controversial

22
00:00:56,830 --> 00:00:54,320
hot dry and dusty saharan air layer

23
00:00:58,630 --> 00:00:56,840
in tropical storm formation and

24
00:01:01,510 --> 00:00:58,640
intensification and the extent to which

25
00:01:03,510 --> 00:01:01,520
the deep convection of the inner core of

26
00:01:06,149 --> 00:01:03,520
those storms

27
00:01:08,789 --> 00:01:06,159
is the key driver of intensity change

28
00:01:11,350 --> 00:01:08,799
the hs3 mentioned will run between

29
00:01:13,510 --> 00:01:11,360
august 20th and september 23rd based at

30
00:01:15,670 --> 00:01:13,520
wallops flight facility in wallops

31
00:01:19,190 --> 00:01:15,680
island virginia

32
00:01:20,710 --> 00:01:19,200
the hs3 mission page is nasa.gov

33
00:01:22,149 --> 00:01:20,720
hs3

34
00:01:24,390 --> 00:01:22,159
we will be taking questions at the end

35
00:01:26,710 --> 00:01:24,400
of the hangout and you can make some

36
00:01:28,070 --> 00:01:26,720

00:01:49,190 --> 00:01:47,360
uh live from the airplane hangar at

44
00:01:51,590 --> 00:01:49,200
dryden so you'll be able to see the

45
00:01:54,630 --> 00:01:51,600
global hawk behind him

46
00:01:55,670 --> 00:01:54,640

52
00:02:09,910 --> 00:02:08,319
capital weather gang columnist so we're

53
00:02:12,550 --> 00:02:09,920
going to start the google hangout by

54
00:02:14,229 --> 00:02:12,560
going over to dr scott brown he's a

55
00:02:15,910 --> 00:02:14,239
research meteorologist here at nasa's

56
00:02:17,350 --> 00:02:15,920
goddard space flight center in greenbelt

57
00:02:19,110 --> 00:02:17,360
and he studies hurricanes from the

58
00:02:20,470 --> 00:02:19,120
inside and out

59
00:02:23,270 --> 00:02:20,480
he was

60
00:02:25,589 --> 00:02:23,280
the hs3 principal mission investigator

61
00:02:28,309 --> 00:02:25,599
last year and again this year um he

62
00:02:29,830 --> 00:02:28,319
leads a diverse team of scientists and

63
00:02:31,110 --> 00:02:29,840
instrument uh

64
00:02:33,430 --> 00:02:31,120
specialists

65
00:02:35,910 --> 00:02:33,440
to investigate hurricanes and conduct

66
00:02:38,470 --> 00:02:35,920
experiments using unmanned aircraft to

67
00:02:40,309 --> 00:02:38,480
better understand the conditions that

68
00:02:43,350 --> 00:02:40,319
favor the storm formation and the

69
00:02:45,670 --> 00:02:43,360
development of major hurricanes and

70
00:02:47,350 --> 00:02:45,680
here's dr scott brown to talk about

71
00:02:50,150 --> 00:02:47,360
what's new with the hs3 mission this

72
00:02:52,710 --> 00:02:50,160
year and the science behind it scott

73
00:02:55,350 --> 00:02:52,720
okay thanks rob well as rob

74
00:02:57,430 --> 00:02:55,360
said we're uh studying the processes

75
00:02:59,509 --> 00:02:57,440
that affect storm formation and

76
00:03:01,430 --> 00:02:59,519
intensity change and we're particularly

77
00:03:03,830 --> 00:03:01,440
interested in the relative roles of the

78
00:03:06,710 --> 00:03:03,840
large scale environment and inner core

79
00:03:09,589 --> 00:03:08,630
and that in terms of the environment one

80
00:03:12,070 --> 00:03:09,599
of the things we're particularly

81
00:03:14,070 --> 00:03:12,080
interested in is the saharan air layer

82
00:03:15,589 --> 00:03:14,080
which has been controversial late

83
00:03:17,430 --> 00:03:15,599
there's been a number of studies early

84
00:03:19,990 --> 00:03:17,440
on that suggests that it can have a

85
00:03:21,830 --> 00:03:20,000
positive influence on storm growth

86
00:03:23,990 --> 00:03:21,840
and that it aids storm formation and

87
00:03:25,830 --> 00:03:24,000
intensification and a number of studies

88
00:03:27,430 --> 00:03:25,840
that suggest that it actually has an

89
00:03:29,030 --> 00:03:27,440
inhibiting effect on storm

90
00:03:31,350 --> 00:03:29,040
intensification

91
00:03:32,789 --> 00:03:31,360
in addition we're very interested in

92
00:03:35,350 --> 00:03:32,799
what happens in the inner core in

93
00:03:37,430 --> 00:03:35,360
particular with very deep thunderstorms

94
00:03:40,309 --> 00:03:37,440
also called hot towers

95
00:03:42,229 --> 00:03:40,319
um and some studies have suggested that

96
00:03:44,470 --> 00:03:42,239
when these hot towers are seen within

97
00:03:46,550 --> 00:03:44,480
the eye wall of a hurricane the storm is

98
00:03:48,630 --> 00:03:46,560
more likely to undergo intensification

99
00:03:50,710 --> 00:03:48,640
in the day that follows whereas if a

100
00:03:53,350 --> 00:03:50,720
tower is not seen

101
00:03:55,670 --> 00:03:53,360
they tend either not to intensify or to

102
00:03:58,470 --> 00:03:55,680
weaken but it's still not clear whether

103
00:04:00,550 --> 00:03:58,480
these hot towers are playing an active

104
00:04:02,229 --> 00:04:00,560
key role in the development or if

105
00:04:04,149 --> 00:04:02,239
they're maybe more of a passive

106
00:04:06,470 --> 00:04:04,159
indicator of other processes that are

107
00:04:08,710 --> 00:04:06,480
leading to the intensification and so

108
00:04:10,390 --> 00:04:08,720
hs3 was really designed to try and look

109
00:04:11,509 --> 00:04:10,400
at both the environmental aspect of the

110
00:04:15,509 --> 00:04:11,519
problem

111
00:04:19,189 --> 00:04:15,519
and to do that we're using two of the

112
00:04:21,189 --> 00:04:19,199
nasa unmanned aircraft uh one uh one

113
00:04:23,189 --> 00:04:21,199
equipped specifically to look at the

114
00:04:26,070 --> 00:04:23,199
environment and i'll describe a little

115
00:04:27,590 --> 00:04:26,080
later the payload that's on there

116
00:04:29,830 --> 00:04:27,600
and the other is equipped with the

117
00:04:31,670 --> 00:04:29,840
payload to really look at the inner core

118
00:04:33,430 --> 00:04:31,680
in particular the precipitation and

119
00:04:35,909 --> 00:04:33,440
winds within the eye wall and the rain

120
00:04:38,150 --> 00:04:35,919
bands uh last year was our first

121
00:04:40,070 --> 00:04:38,160
deployment uh and

122
00:04:43,510 --> 00:04:40,080
in that deployment out of walls we only

123
00:04:44,629 --> 00:04:43,520
had the environmental aircraft

124
00:04:46,469 --> 00:04:44,639
and

125
00:04:48,070 --> 00:04:46,479
that was probably due to some logistical

126
00:04:51,110 --> 00:04:48,080
and technical uh

127
00:04:54,150 --> 00:04:51,120
issues with the other aircraft excuse me

128
00:04:56,070 --> 00:04:54,160
your blood just fell out

129
00:04:57,990 --> 00:04:56,080
but it proved extremely useful having

130
00:05:00,230 --> 00:04:58,000
that one aircraft to work out a number

131
00:05:02,870 --> 00:05:00,240
of the issues involved in a very complex

132
00:05:05,110 --> 00:05:02,880
operation uh operating out of walls for

133
00:05:07,830 --> 00:05:05,120
the very first time um

134
00:05:09,830 --> 00:05:07,840
with a global hawk uh with a science

135
00:05:13,189 --> 00:05:09,840
team that had never

136
00:05:14,870 --> 00:05:13,199
done this type of campaign

137
00:05:16,710 --> 00:05:14,880
in just this sort of way so it was

138
00:05:18,310 --> 00:05:16,720
really a challenge

139
00:05:21,029 --> 00:05:18,320
we had

140
00:05:22,870 --> 00:05:21,039
six flights that were done last year

141
00:05:25,270 --> 00:05:22,880
the first one was actually our transit

142
00:05:27,270 --> 00:05:25,280
flight from dryden out to wallops uh

143
00:05:29,189 --> 00:05:27,280
hurricane leslie was out in the western

144
00:05:32,150 --> 00:05:29,199
atlantic at the time and we decided to

145
00:05:34,070 --> 00:05:32,160
fly around uh the outskirts of leslie to

146
00:05:35,670 --> 00:05:34,080
look at its outflow layer and that was

147
00:05:37,990 --> 00:05:35,680
our very first flight we got some very

148
00:05:40,310 --> 00:05:38,000
unique observations in the outflow layer

149
00:05:42,230 --> 00:05:40,320
uh from the probably for the first time

150
00:05:44,710 --> 00:05:42,240
from above the storm all the way through

151
00:05:47,110 --> 00:05:44,720
the alpha layer and down to the surface

152
00:05:50,950 --> 00:05:47,120
our next five flights were into a very

153
00:05:52,790 --> 00:05:50,960
long-lived hurricane nadine uh which uh

154
00:05:54,550 --> 00:05:52,800
the first flight being when it first

155
00:05:56,629 --> 00:05:54,560
became a tropical storm the second

156
00:05:58,150 --> 00:05:56,639
flight when it first became a hurricane

157
00:05:59,749 --> 00:05:58,160
and then if you remember hurricane

158
00:06:02,390 --> 00:05:59,759
nadine moved out into the eastern

159
00:06:04,070 --> 00:06:02,400
atlantic around the azores and just sort

160
00:06:06,469 --> 00:06:04,080
of meandered out there for almost two

161
00:06:08,070 --> 00:06:06,479
weeks or about two weeks and we were

162
00:06:09,830 --> 00:06:08,080
able to do three flights during that

163
00:06:11,430 --> 00:06:09,840
time something that you really wouldn't

164
00:06:13,110 --> 00:06:11,440
be able to do with the manned aircraft

165
00:06:15,110 --> 00:06:13,120
because of the range and duration of the

166
00:06:16,469 --> 00:06:15,120
global hawk

167
00:06:18,070 --> 00:06:16,479
and during that time we saw the

168
00:06:19,909 --> 00:06:18,080
weakening of the storm when it went

169
00:06:21,990 --> 00:06:19,919
post-tropical and then we saw its

170
00:06:24,469 --> 00:06:22,000
redevelopment including

171
00:06:26,629 --> 00:06:24,479
the onset of its re-intensification back

172
00:06:28,469 --> 00:06:26,639
into a hurricane and it subsequently

173
00:06:30,309 --> 00:06:28,479
reached its maximum intensity over its

174
00:06:32,230 --> 00:06:30,319
entire life cycle

175
00:06:33,749 --> 00:06:32,240
so we got some very unique measurements

176
00:06:35,590 --> 00:06:33,759
last year

177
00:06:38,390 --> 00:06:35,600
now this year we're adding in the second

178
00:06:40,230 --> 00:06:38,400
aircraft which will have uh the suite of

179
00:06:41,350 --> 00:06:40,240
instruments designed to look at the

180
00:06:43,110 --> 00:06:41,360
inner core

181
00:06:45,830 --> 00:06:43,120
uh and and by

182
00:06:48,230 --> 00:06:45,840
taking using the the two planes uh

183
00:06:50,230 --> 00:06:48,240
potentially one right after the other

184
00:06:52,469 --> 00:06:50,240
will be able to get snapshots of the

185
00:06:54,230 --> 00:06:52,479
environment i shouldn't say snapshot

186
00:06:56,150 --> 00:06:54,240
shots but continuous looks at the

187
00:06:57,830 --> 00:06:56,160
environment and then the inner core and

188
00:07:00,710 --> 00:06:57,840
then potentially going back and forth

189
00:07:02,309 --> 00:07:00,720
between the two with time in between uh

190
00:07:04,309 --> 00:07:02,319
for crew rest given the the long

191
00:07:05,589 --> 00:07:04,319
duration of these flights

192
00:07:07,270 --> 00:07:05,599
um

193
00:07:09,830 --> 00:07:07,280
rob if you guys want to show the

194
00:07:11,189 --> 00:07:09,840
interactive on the uh the instruments i

195
00:07:13,670 --> 00:07:11,199
can talk a little bit about the payload

196
00:07:20,550 --> 00:07:13,680
or we can pause a moment and discuss

197
00:07:23,909 --> 00:07:22,309
okay let's uh let's pull up the

198
00:07:30,950 --> 00:07:23,919
interactive um

199
00:07:34,309 --> 00:07:32,309
all right as we wait for the uh the

200
00:07:36,629 --> 00:07:34,319
interactive um

201
00:07:38,950 --> 00:07:36,639
the the uh the unmanned aircraft will

202
00:07:41,029 --> 00:07:38,960
actually be able to to go for twice as

203
00:07:42,710 --> 00:07:41,039
long as a hurricane hunter aircraft is

204
00:07:44,150 --> 00:07:42,720
that is that correct scott

205
00:07:46,870 --> 00:07:44,160
uh a lot of it

206
00:07:49,189 --> 00:07:46,880
its total flight duration is uh two to

207
00:07:51,830 --> 00:07:49,199
three times as long as a typical manned

208
00:07:53,830 --> 00:07:51,840
aircraft uh depending on where the storm

209
00:07:55,670 --> 00:07:53,840
is in the atlantic will either be if

210
00:07:58,070 --> 00:07:55,680
it's close to the u.s we'll be able to

211
00:07:59,670 --> 00:07:58,080
spend maybe two to three times as much

212
00:08:01,670 --> 00:07:59,680
time over the storm as you would with

213
00:08:03,350 --> 00:08:01,680
the manned aircraft but if it's out in

214
00:08:05,350 --> 00:08:03,360
the central atlantic we can actually get

215
00:08:07,270 --> 00:08:05,360
the storms that we wouldn't normally get

216
00:08:09,510 --> 00:08:07,280
to with manned aircraft because of the

217
00:08:10,950 --> 00:08:09,520
long range and nadine was a good example

218
00:08:12,710 --> 00:08:10,960
that where it was in the northeastern

219
00:08:15,110 --> 00:08:12,720
atlantic and we were able to spend 10 to

220
00:08:16,390 --> 00:08:15,120
12 hours over the storm whereas a manned

221
00:08:18,469 --> 00:08:16,400
aircraft really would not have been able

222
00:08:19,350 --> 00:08:18,479
to get to it and spend any time at all

223
00:08:21,990 --> 00:08:19,360
in it

224
00:08:24,629 --> 00:08:22,000
so that is a real advantage of the

225
00:08:27,589 --> 00:08:26,070
and and this year we'll we're actually

226
00:08:30,390 --> 00:08:27,599
going to be double teaming with the two

227
00:08:31,830 --> 00:08:30,400
global hawks uh one to get the data from

228
00:08:33,589 --> 00:08:31,840
the guts of the storm and the other

229
00:08:34,870 --> 00:08:33,599
basically to look at the the whole

230
00:08:37,350 --> 00:08:34,880
environment

231
00:08:40,709 --> 00:08:37,360
um of the storm so that's something we

232
00:08:42,870 --> 00:08:40,719
weren't able to do last year right

233
00:08:44,710 --> 00:08:42,880
is that interactive ready

234
00:08:47,990 --> 00:08:44,720
i can kind of

235
00:08:48,000 --> 00:08:58,389
we are bringing the uh

236
00:09:03,590 --> 00:09:00,790
let's um let's take

237
00:09:05,670 --> 00:09:03,600
let's turn to uh to some of the the uh

238
00:09:07,030 --> 00:09:05,680
instruments on the on the global hawks

239
00:09:09,030 --> 00:09:07,040
as we wait for the interactive to come

240
00:09:11,670 --> 00:09:09,040
up well that's what i was hoping for the

241
00:09:14,230 --> 00:09:11,680
interactive for but uh

242
00:09:16,470 --> 00:09:14,240
one thing we can say is uh as we're

243
00:09:18,150 --> 00:09:16,480
doing these flights we're interacting uh

244
00:09:20,470 --> 00:09:18,160
quite a bit with noah

245
00:09:22,070 --> 00:09:20,480
noah is one of our

246
00:09:25,030 --> 00:09:22,080
team members they provide one of the

247
00:09:27,030 --> 00:09:25,040
instruments uh and the the the sort of

248
00:09:29,269 --> 00:09:27,040
the manpower behind operating the

249
00:09:30,630 --> 00:09:29,279
instrument and processing the data uh in

250
00:09:32,389 --> 00:09:30,640
addition they're providing a few of the

251
00:09:35,269 --> 00:09:32,399
pilots and some of the ground crews

252
00:09:37,030 --> 00:09:35,279
they're a significant partner for us um

253
00:09:38,470 --> 00:09:37,040
in addition to that

254
00:09:40,389 --> 00:09:38,480
the noaa

255
00:09:45,190 --> 00:09:40,399
hurricane hunter aircraft

256
00:09:46,790 --> 00:09:45,200
will be out there at the same time and

257
00:09:48,389 --> 00:09:46,800
we are planning to

258
00:09:50,550 --> 00:09:48,399
collaborate with them as much as

259
00:09:51,910 --> 00:09:50,560
possible to try to time our flight so

260
00:09:54,070 --> 00:09:51,920
that we're either flying together to

261
00:09:57,990 --> 00:09:54,080
maximize the data being collected at any

262
00:10:01,910 --> 00:10:00,550
in series with each other so that we

263
00:10:03,990 --> 00:10:01,920
maintain

264
00:10:07,750 --> 00:10:04,000
as continuous coverage of the storm as

265
00:10:09,829 --> 00:10:08,550
so

266
00:10:11,110 --> 00:10:09,839
if the interactive it's not going to be

267
00:10:12,550 --> 00:10:11,120
off i can just

268
00:10:14,230 --> 00:10:12,560
it's alright it's up and running you

269
00:10:19,750 --> 00:10:14,240
just just look on the bottom of your

270
00:10:24,230 --> 00:10:21,750
all right so um this is our

271
00:10:27,030 --> 00:10:24,240
environmental aircraft it has uh three

272
00:10:29,350 --> 00:10:27,040
instruments on it for 2013.

273
00:10:31,750 --> 00:10:29,360
the first is the cloud physics lidar

274
00:10:35,590 --> 00:10:31,760
which is up in the nose of the aircraft

275
00:10:37,910 --> 00:10:35,600
it's specifically designed to look at

276
00:10:39,110 --> 00:10:37,920
profiles of saharan dust which is one of

277
00:10:40,870 --> 00:10:39,120
the things that we're trying to track

278
00:10:42,790 --> 00:10:40,880
and how it interacts with the storm so

279
00:10:44,389 --> 00:10:42,800
this gives us a way to identify where

280
00:10:46,550 --> 00:10:44,399
the saharan air

281
00:10:49,829 --> 00:10:46,560
air layer air mass is

282
00:10:51,110 --> 00:10:49,839
um a second instrument uh in the belly

283
00:10:52,949 --> 00:10:51,120
of the aircraft although it lifts

284
00:10:54,310 --> 00:10:52,959
twilight there uh that's one that we're

285
00:10:55,509 --> 00:10:54,320
not actually flying this year but

286
00:10:57,829 --> 00:10:55,519
there's another instrument that's going

287
00:11:00,069 --> 00:10:57,839
to be there called scanning his or the

288
00:11:02,150 --> 00:11:00,079
interferometer sounder that'll give us

289
00:11:04,470 --> 00:11:02,160
vertical profiles of temperature and

290
00:11:06,550 --> 00:11:04,480
humidity in the clear air environment

291
00:11:09,350 --> 00:11:06,560
and then when we're overflying clouds it

292
00:11:11,509 --> 00:11:09,360
gives us information uh on the

293
00:11:13,430 --> 00:11:11,519
properties of the cloud tops

294
00:11:15,670 --> 00:11:13,440
and then at the back of the aircraft

295
00:11:17,350 --> 00:11:15,680
there's an instrument known as avaps

296
00:11:19,910 --> 00:11:17,360
which is a drop sonde system so it

297
00:11:22,069 --> 00:11:19,920
releases a small tube from the aircraft

298
00:11:24,150 --> 00:11:22,079
that floats down to the surface on a

299
00:11:25,990 --> 00:11:24,160
parachute and as it's going down it

300
00:11:28,230 --> 00:11:26,000
collects information on temperature

301
00:11:30,230 --> 00:11:28,240
humidity pressure wind speed and

302
00:11:32,150 --> 00:11:30,240
direction with very high vertical

303
00:11:33,509 --> 00:11:32,160
resolution so we get very detailed

304
00:11:36,230 --> 00:11:33,519
measurements of some of the vertical

305
00:11:38,069 --> 00:11:36,240
structures uh and that's one one of the

306
00:11:40,389 --> 00:11:38,079
instruments that we also then can feed

307
00:11:41,750 --> 00:11:40,399
in to some of the operational centers

308
00:11:43,350 --> 00:11:41,760
and potentially into some of the

309
00:11:45,269 --> 00:11:43,360
forecast models

310
00:11:46,550 --> 00:11:45,279
now we had also planned to fly a wind

311
00:11:48,230 --> 00:11:46,560
lighter that would have been in the

312
00:11:51,110 --> 00:11:48,240
belly of the aircraft that would provide

313
00:11:53,829 --> 00:11:51,120
continuous wind uh speed and direction

314
00:11:55,269 --> 00:11:53,839
uh measurements in the clear air

315
00:11:58,389 --> 00:11:55,279
but there's been some issues with that

316
00:12:00,550 --> 00:11:58,399
that we haven't been able to fly yet

317
00:12:03,670 --> 00:12:00,560
i guess i won't get into that part uh if

318
00:12:06,150 --> 00:12:03,680
you can go to the other aircraft um

319
00:12:08,790 --> 00:12:06,160
our overstorm aircraft is carrying

320
00:12:13,030 --> 00:12:08,800
um the plan three instruments which are

321
00:12:15,350 --> 00:12:13,040
uh hamster in the nose of the aircraft

322
00:12:18,470 --> 00:12:15,360
it's a microwave sounder

323
00:12:20,870 --> 00:12:18,480
that's capable of giving us uh sort of

324
00:12:23,030 --> 00:12:20,880
low resolution vertical profiles of

325
00:12:25,269 --> 00:12:23,040
temperature and humidity in both clear

326
00:12:26,790 --> 00:12:25,279
and cloudy air and then when we're in

327
00:12:28,150 --> 00:12:26,800
precipitating areas it gives us

328
00:12:30,310 --> 00:12:28,160
information on the vertical

329
00:12:33,430 --> 00:12:30,320
precipitation profiles

330
00:12:35,590 --> 00:12:33,440
in the belly of the aircraft is a dual

331
00:12:37,509 --> 00:12:35,600
frequency conically scanning doppler

332
00:12:40,389 --> 00:12:37,519
radar so this provides

333
00:12:43,030 --> 00:12:40,399
information on both winds wind speed and

334
00:12:44,870 --> 00:12:43,040
direction and precipitation profiles

335
00:12:46,629 --> 00:12:44,880
within the storm and then when we're

336
00:12:48,870 --> 00:12:46,639
outside of precipitation areas it can

337
00:12:51,110 --> 00:12:48,880
give us wind speed and direction

338
00:12:52,629 --> 00:12:51,120
at the surface to look at the overall

339
00:12:55,030 --> 00:12:52,639
surface flow

340
00:12:56,710 --> 00:12:55,040
and then in the tail the aircraft is an

341
00:12:58,629 --> 00:12:56,720
instrument it's a

342
00:13:01,269 --> 00:12:58,639
microwave radiometer

343
00:13:03,990 --> 00:13:01,279
that gives us a broad swath of surface

344
00:13:05,910 --> 00:13:04,000
wind speed and precipitation information

345
00:13:07,670 --> 00:13:05,920
so in one pass of the storm we'll be

346
00:13:10,949 --> 00:13:07,680
able to map out the surface wind speed

347
00:13:12,629 --> 00:13:10,959
field and look at the the structure of

348
00:13:14,949 --> 00:13:12,639
the of the wind maximum

349
00:13:16,310 --> 00:13:14,959
how broad the wind speed maximum is and

350
00:13:17,430 --> 00:13:16,320
things of that sort

351
00:13:19,110 --> 00:13:17,440
now this year it's not on the

352
00:13:20,550 --> 00:13:19,120
interactive diagram but we're also

353
00:13:22,790 --> 00:13:20,560
flying what we call a piggyback

354
00:13:25,670 --> 00:13:22,800
instrument something that

355
00:13:28,150 --> 00:13:25,680
got itself funded to ride along with us

356
00:13:30,710 --> 00:13:28,160
and it's a gamma-ray detector looking at

357
00:13:32,949 --> 00:13:30,720
gamma rays emitted from lightning

358
00:13:34,470 --> 00:13:32,959
within the storm so those those are the

359
00:13:39,509 --> 00:13:34,480
instruments that we have for for this

360
00:13:44,710 --> 00:13:42,310
come back to your rob thank you scott

361
00:13:47,590 --> 00:13:44,720
um just a reminder we are taking

362
00:13:50,150 --> 00:13:47,600
questions um and you can make comments

363
00:13:52,310 --> 00:13:50,160
or or questions on youtube uh you can

364
00:13:53,509 --> 00:13:52,320
make them on twitter using

365
00:13:56,870 --> 00:13:53,519
nasa

366
00:13:57,990 --> 00:13:56,880
hs3 and also uh comments will be taken

367
00:13:59,910 --> 00:13:58,000
on the google

368
00:14:01,189 --> 00:13:59,920
google plus page and we will get to your

369
00:14:02,470 --> 00:14:01,199
questions and answers at the end of the

370
00:14:04,710 --> 00:14:02,480
session

371
00:14:07,829 --> 00:14:04,720
now i'd like to move on to nasa dryden

372
00:14:09,430 --> 00:14:07,839
and uh to tom miller a project pilot for

373
00:14:11,430 --> 00:14:09,440
the global hawk who is sitting in the

374
00:14:13,910 --> 00:14:11,440
hangar with the global hawk uh behind

375
00:14:16,949 --> 00:14:13,920
him uh tom miller is a project pilot for

376
00:14:19,750 --> 00:14:16,959
the uh the unmanned spacecraft

377
00:14:22,230 --> 00:14:19,760
at edwards california and he determines

378
00:14:24,790 --> 00:14:22,240
training objectives and standards

379
00:14:26,069 --> 00:14:24,800
he evaluates air crew performance and he

380
00:14:27,990 --> 00:14:26,079
is a subject matter expert for

381
00:14:30,790 --> 00:14:28,000
development on the ground station and

382
00:14:33,430 --> 00:14:30,800
command and control communication system

383
00:14:35,189 --> 00:14:33,440
that's used to fly the aircraft so tom

384
00:14:36,870 --> 00:14:35,199
uh tell us about the aircraft

385
00:14:39,030 --> 00:14:36,880
operational

386
00:14:40,629 --> 00:14:39,040
okay well uh just uh i'll begin with a

387
00:14:42,069 --> 00:14:40,639
description of the airplane itself and

388
00:14:43,350 --> 00:14:42,079
let everybody get a look at the whole

389
00:14:46,150 --> 00:14:43,360
thing here

390
00:14:48,550 --> 00:14:46,160
this is actually uh air vehicle one this

391
00:14:50,550 --> 00:14:48,560
was the aircraft that

392
00:14:53,910 --> 00:14:50,560
ryan first flew the first global hawk to

393
00:14:56,069 --> 00:14:53,920
fly back in 1998. so we resurrected it

394
00:14:58,870 --> 00:14:56,079
for a nasa science mission and it's

395
00:15:00,310 --> 00:14:58,880
still going strong

396
00:15:02,550 --> 00:15:00,320
we um

397
00:15:04,949 --> 00:15:02,560
as uh scott talked about there we

398
00:15:06,629 --> 00:15:04,959
develop our mission plans in conjunction

399
00:15:08,470 --> 00:15:06,639
with the scientists typically a couple

400
00:15:10,389 --> 00:15:08,480
days prior to the flight

401
00:15:12,389 --> 00:15:10,399
we'll go ahead and start working with

402
00:15:13,670 --> 00:15:12,399
the science team and up up to about the

403
00:15:15,509 --> 00:15:13,680
day prior

404
00:15:16,710 --> 00:15:15,519
we'll finalize this and turn it into a

405
00:15:18,389 --> 00:15:16,720
flight plan

406
00:15:19,990 --> 00:15:18,399
then we'll also on that day we'll also

407
00:15:22,069 --> 00:15:20,000
be coordinating with the air traffic

408
00:15:23,590 --> 00:15:22,079
authorities and lining up everything to

409
00:15:27,110 --> 00:15:23,600
conduct the mission

410
00:15:29,590 --> 00:15:27,120
the day of flight uh will show up about

411
00:15:31,269 --> 00:15:29,600
three hours prior to flight time to our

412
00:15:33,829 --> 00:15:31,279
briefing to our pre-flights and prepare

413
00:15:35,350 --> 00:15:33,839
the aircraft uh during all the time this

414
00:15:37,269 --> 00:15:35,360
is going on the ground crew has been

415
00:15:40,310 --> 00:15:37,279
working really hard uh getting the

416
00:15:42,310 --> 00:15:40,320
aircraft ready ready to go

417
00:15:44,150 --> 00:15:42,320
so we'll conduct the pre-flight

418
00:15:46,790 --> 00:15:44,160
and then we go ahead and launch the

419
00:15:48,230 --> 00:15:46,800
aircraft using local command and control

420
00:15:50,790 --> 00:15:48,240
links

421
00:15:52,550 --> 00:15:50,800
about three hours after the launch we'll

422
00:15:54,870 --> 00:15:52,560
be driving out to the

423
00:15:57,430 --> 00:15:54,880
mission area we'll go ahead and hand off

424
00:15:58,710 --> 00:15:57,440
the aircraft back to a crew here at

425
00:16:00,470 --> 00:15:58,720
dryden

426
00:16:02,629 --> 00:16:00,480
that's in our global hawk operations

427
00:16:05,350 --> 00:16:02,639
center and they will take over the

428
00:16:07,509 --> 00:16:05,360
aircraft and either continue enroute to

429
00:16:09,829 --> 00:16:07,519
the mission area depending on how close

430
00:16:11,670 --> 00:16:09,839
the missionary is or or go ahead and

431
00:16:13,110 --> 00:16:11,680
start right into the into the science

432
00:16:15,350 --> 00:16:13,120
bush

433
00:16:17,910 --> 00:16:15,360
this crew will do a shift of about uh

434
00:16:19,430 --> 00:16:17,920
nine to ten hours they'll hand it off to

435
00:16:21,350 --> 00:16:19,440
another crew

436
00:16:22,949 --> 00:16:21,360
who again does another nine or ten hours

437
00:16:25,990 --> 00:16:22,959
of doing the scientists

438
00:16:27,910 --> 00:16:26,000
and again we'll either continue that or

439
00:16:30,069 --> 00:16:27,920
depending on where the storm is we'll

440
00:16:33,189 --> 00:16:30,079
start to drive home

441
00:16:34,230 --> 00:16:33,199
approximately four hours prior to uh

442
00:16:35,990 --> 00:16:34,240
landing

443
00:16:38,949 --> 00:16:36,000
they'll hand the aircraft back off to

444
00:16:40,790 --> 00:16:38,959
the crew at wallops the recovery crew

445
00:16:43,749 --> 00:16:40,800
and that crew will then uh effectively

446
00:16:46,629 --> 00:16:43,759
join up with the chase aircraft and

447
00:16:49,110 --> 00:16:46,639
go ahead and land

448
00:16:50,710 --> 00:16:49,120
so as far as how the airplane flies it's

449
00:16:52,550 --> 00:16:50,720
very similar to flying any other

450
00:16:55,430 --> 00:16:52,560
airplane though just kind of a full-time

451
00:16:57,990 --> 00:16:55,440
autopilot we drive the airplane around

452
00:17:00,310 --> 00:16:58,000
and work at work scientists to achieve

453
00:17:03,430 --> 00:17:00,320
whatever objectives they need to

454
00:17:07,590 --> 00:17:05,110
and again the mission depends on whether

455
00:17:09,990 --> 00:17:07,600
we're flying the overstorm aircraft or

456
00:17:12,710 --> 00:17:10,000
the environmental aircraft as to how

457
00:17:15,189 --> 00:17:12,720
complicated it is

458
00:17:18,630 --> 00:17:16,309
let's see

459
00:17:20,870 --> 00:17:18,640
uh what else can i talk about here about

460
00:17:24,870 --> 00:17:23,189
airplane uh some of the challenges that

461
00:17:27,350 --> 00:17:24,880
we talked about and the advantages

462
00:17:29,270 --> 00:17:27,360
obviously one of the advantages of using

463
00:17:30,789 --> 00:17:29,280
an unmanned aircraft is that we do have

464
00:17:33,430 --> 00:17:30,799
the endurance you don't have to carry a

465
00:17:36,310 --> 00:17:33,440
full crew

466
00:17:38,230 --> 00:17:36,320
we swap out during uh during the flight

467
00:17:40,470 --> 00:17:38,240
so that's uh that's a big advantage that

468
00:17:42,710 --> 00:17:40,480
this aircraft offers whereas a manned

469
00:17:44,870 --> 00:17:42,720
aircraft is typically limited to

470
00:17:46,789 --> 00:17:44,880
through the endurance of the aircrew we

471
00:17:47,990 --> 00:17:46,799
can change ours out right in the middle

472
00:17:49,830 --> 00:17:48,000
to mission

473
00:17:51,510 --> 00:17:49,840
but this also brings some challenges in

474
00:17:53,830 --> 00:17:51,520
that it is an unmanned aircraft and

475
00:17:55,909 --> 00:17:53,840
we're still trying to fully integrate uh

476
00:17:58,150 --> 00:17:55,919
in the airspace with the other manned

477
00:17:59,430 --> 00:17:58,160
aircraft so that's proved to be a

478
00:18:02,549 --> 00:17:59,440
challenge but we've got a really good

479
00:18:04,549 --> 00:18:02,559
relationship with the faa and the oceana

480
00:18:06,150 --> 00:18:04,559
control authorities and

481
00:18:10,870 --> 00:18:06,160
they've really helped us out a lot we've

482
00:18:10,880 --> 00:18:15,430
to continue doing that

483
00:18:20,549 --> 00:18:17,750
thank you tom so i have a question for

484
00:18:23,430 --> 00:18:20,559
you the uh in terms of the duration of

485
00:18:25,270 --> 00:18:23,440
global hawks uh how long can they stay

486
00:18:26,950 --> 00:18:25,280
in the air

487
00:18:28,950 --> 00:18:26,960
well of course

488
00:18:31,110 --> 00:18:28,960
yeah this depends on how the aircraft is

489
00:18:34,150 --> 00:18:31,120
loaded but uh general uh flight time is

490
00:18:36,470 --> 00:18:34,160
about 28 hours

491
00:18:39,669 --> 00:18:36,480
and what altitude did they fly at we'll

492
00:18:41,909 --> 00:18:39,679
go uh well above 60 000 feet

493
00:18:44,310 --> 00:18:41,919
we get to a cruise climb altitude based

494
00:18:46,950 --> 00:18:44,320
on weight and at that point we have to

495
00:18:47,750 --> 00:18:46,960
burn off more fuel to continue climbing

496
00:18:50,549 --> 00:18:47,760
so

497
00:18:52,870 --> 00:18:50,559
it achieves an initial altitude and then

498
00:18:56,070 --> 00:18:52,880
just does this kind of slow climb up to

499
00:18:58,230 --> 00:18:56,080
the ultimate ceiling

500
00:19:01,590 --> 00:18:58,240
so what is it like piloting the global

501
00:19:03,510 --> 00:19:01,600
hawk from where you are

502
00:19:04,950 --> 00:19:03,520
well it's a little strange you in in

503
00:19:07,750 --> 00:19:04,960
some cases you're you're a little

504
00:19:10,310 --> 00:19:07,760
disconnected um from the aircraft you

505
00:19:12,630 --> 00:19:10,320
don't have the same sensations that uh

506
00:19:14,150 --> 00:19:12,640
you would in a manned aircraft uh you

507
00:19:15,990 --> 00:19:14,160
don't have uh

508
00:19:17,510 --> 00:19:16,000
you know

509
00:19:19,430 --> 00:19:17,520
sound uh

510
00:19:21,430 --> 00:19:19,440
the sound of the aircraft the sound of

511
00:19:24,230 --> 00:19:21,440
the engines the seat of the pants

512
00:19:25,590 --> 00:19:24,240
sensations the g-forces that uh come on

513
00:19:27,830 --> 00:19:25,600
an airplane when you're flying you know

514
00:19:29,590 --> 00:19:27,840
if uh if something were to go wrong for

515
00:19:31,909 --> 00:19:29,600
example and the engine were to roll back

516
00:19:33,590 --> 00:19:31,919
you don't hear that as you would in a

517
00:19:36,630 --> 00:19:33,600
manned aircraft so that brings its own

518
00:19:38,310 --> 00:19:36,640
challenges basically we all we have this

519
00:19:39,510 --> 00:19:38,320
site let's project on the computer

520
00:19:41,750 --> 00:19:39,520
screen so

521
00:19:44,150 --> 00:19:41,760
it's a bit like flying uh any other

522
00:19:46,310 --> 00:19:44,160
aircraft put on a full-time auto pilot

523
00:19:48,150 --> 00:19:46,320
we don't have direct uh control over the

524
00:19:51,430 --> 00:19:48,160
flight controls but we give the aircraft

525
00:19:53,830 --> 00:19:51,440
altitude headings and air speeds and the

526
00:19:55,430 --> 00:19:53,840
mission management computers decide how

527
00:19:57,510 --> 00:19:55,440
to hit the airplane

528
00:19:59,669 --> 00:19:57,520
where we asked it to go

529
00:20:00,630 --> 00:19:59,679
and it's 60 000 feet you're well over

530
00:20:02,070 --> 00:20:00,640
the top of

531
00:20:04,870 --> 00:20:02,080
a tropical storm

532
00:20:07,350 --> 00:20:04,880
uh generally we are yes

533
00:20:10,070 --> 00:20:07,360
so last year i understand that uh during

534
00:20:12,150 --> 00:20:10,080
hurricane nadine we dropped somewhere in

535
00:20:13,909 --> 00:20:12,160
the vicinity of 300 drop songs is that

536
00:20:15,510 --> 00:20:13,919
correct

537
00:20:17,430 --> 00:20:15,520
so that they provided a lot of

538
00:20:18,950 --> 00:20:17,440
information that we otherwise couldn't

539
00:20:21,350 --> 00:20:18,960
get

540
00:20:23,350 --> 00:20:21,360
uh yeah it sure did i i think scott you

541
00:20:26,070 --> 00:20:23,360
know probably speak more to the data

542
00:20:28,230 --> 00:20:26,080
that was collected than i could

543
00:20:32,630 --> 00:20:28,240
yeah i think overall we collected about

544
00:20:34,470 --> 00:20:32,640
350 uh drops on uh profiles

545
00:20:36,549 --> 00:20:34,480
the drop sign instruments capable of

546
00:20:38,470 --> 00:20:36,559
carrying up to 88 suns in a single

547
00:20:40,870 --> 00:20:38,480
flight i think the most that we did was

548
00:20:43,270 --> 00:20:40,880
around 75 77 last year in a single

549
00:20:47,669 --> 00:20:45,510
scott can you explain uh for the viewers

550
00:20:49,590 --> 00:20:47,679
what a drop sonde is and what what it

551
00:20:50,390 --> 00:20:49,600
tells us

552
00:20:52,630 --> 00:20:50,400
uh

553
00:20:55,029 --> 00:20:52,640
yeah i thought i did earlier but

554
00:20:57,029 --> 00:20:55,039
so basically again it's a small tube uh

555
00:20:59,350 --> 00:20:57,039
that has a parachute at one end and a

556
00:21:01,270 --> 00:20:59,360
sensor at the other end and it's ejected

557
00:21:03,510 --> 00:21:01,280
from the aircraft craft it's a fairly

558
00:21:04,630 --> 00:21:03,520
lightweight tube

559
00:21:06,070 --> 00:21:04,640
about the

560
00:21:09,909 --> 00:21:06,080
you know maybe an inch and a half in

561
00:21:11,669 --> 00:21:09,919
diameter and uh maybe 15 inches long

562
00:21:13,909 --> 00:21:11,679
and as it falls to the surface on this

563
00:21:16,149 --> 00:21:13,919
small with the small parachute

564
00:21:18,310 --> 00:21:16,159
it's collecting temperature pressure uh

565
00:21:19,270 --> 00:21:18,320
wind speed relative humidity and wind

566
00:21:20,870 --> 00:21:19,280
direction

567
00:21:23,190 --> 00:21:20,880
uh and then when it hits the surface

568
00:21:25,110 --> 00:21:23,200
it's it stops collecting data

569
00:21:28,549 --> 00:21:25,120
but it basically gives us a very high

570
00:21:33,590 --> 00:21:28,559
resolution profile of those parameters

571
00:21:37,190 --> 00:21:34,789
thank you scott

572
00:21:39,029 --> 00:21:37,200
um back to you tom anything you want to

573
00:21:41,029 --> 00:21:39,039
add

574
00:21:43,669 --> 00:21:41,039
i don't think so maybe i'll uh save it

575
00:21:45,350 --> 00:21:43,679
for uh some questions and answers later

576
00:21:46,789 --> 00:21:45,360
okay

577
00:21:49,029 --> 00:21:46,799
very good thank you and that's a

578
00:21:50,710 --> 00:21:49,039
beautiful aircraft behind you

579
00:21:53,270 --> 00:21:50,720
again just a reminder for those who are

580
00:21:55,750 --> 00:21:53,280
are watching us on youtube or

581
00:21:57,590 --> 00:21:55,760
on google plus you can comment on both

582
00:21:58,870 --> 00:21:57,600
of those and also on twitter with

583
00:22:01,909 --> 00:21:58,880
hashtag

584
00:22:03,750 --> 00:22:01,919
nasa hs3

585
00:22:06,549 --> 00:22:03,760
next we're going to take you to marilyn

586
00:22:09,270 --> 00:22:06,559
vasquez she's the hs3 project manager

587
00:22:11,190 --> 00:22:09,280
and she has been leading more than 200

588
00:22:13,350 --> 00:22:11,200
people will be involved in preparing and

589
00:22:15,430 --> 00:22:13,360
supporting the aircraft so she's going

590
00:22:18,149 --> 00:22:15,440
to tell us what it takes to get the

591
00:22:19,430 --> 00:22:18,159
flight off the ground

592
00:22:22,390 --> 00:22:19,440
marilyn does flight planning and

593
00:22:25,110 --> 00:22:22,400
aircraft coordination and she conducts

594
00:22:27,830 --> 00:22:25,120
the science data collection which is a

595
00:22:30,230 --> 00:22:27,840
big job all in itself um all this work

596
00:22:31,909 --> 00:22:30,240
is done to support the hs3 mission

597
00:22:34,310 --> 00:22:31,919
which has the two global hawks as we've

598
00:22:35,990 --> 00:22:34,320
been talking about and uh carry these

599
00:22:38,230 --> 00:22:36,000
these science instruments over

600
00:22:39,830 --> 00:22:38,240
hurricanes and tropical cyclones so

601
00:22:41,270 --> 00:22:39,840
marilyn tell us about flight planning

602
00:22:43,270 --> 00:22:41,280
and what it takes to get a flight off

603
00:22:44,870 --> 00:22:43,280
the ground

604
00:22:47,110 --> 00:22:44,880
all right um

605
00:22:49,110 --> 00:22:47,120
getting some echo here um anyway i

606
00:22:51,029 --> 00:22:49,120
wanted to let you know that uh this

607
00:22:52,630 --> 00:22:51,039
whole project is a

608
00:22:54,470 --> 00:22:52,640
great amount of coordination

609
00:22:57,190 --> 00:22:54,480
communication and planning that's how we

610
00:22:59,270 --> 00:22:57,200
do this we have i worked the project

611
00:23:01,590 --> 00:22:59,280
development with scott

612
00:23:03,110 --> 00:23:01,600
and then with the global hawk team at

613
00:23:06,310 --> 00:23:03,120
dryden for all of

614
00:23:08,630 --> 00:23:06,320
the operations and then also with our

615
00:23:11,430 --> 00:23:08,640
hosts here at wallops for the logistics

616
00:23:13,510 --> 00:23:11,440
and operations for flying the plane

617
00:23:14,630 --> 00:23:13,520
so do you have that um yes i see you've

618
00:23:18,630 --> 00:23:14,640
got the

619
00:23:22,950 --> 00:23:21,029
so what i'm showing you here if it comes

620
00:23:25,510 --> 00:23:22,960
up

621
00:23:27,190 --> 00:23:25,520
are you guys seeing it

622
00:23:29,750 --> 00:23:27,200
anyway it's going it's the integration

623
00:23:32,789 --> 00:23:29,760
of the environmental aircraft you're

624
00:23:35,669 --> 00:23:32,799
going to see them uh load scanning his

625
00:23:37,110 --> 00:23:35,679
into the belly of the plane then cpl

626
00:23:39,190 --> 00:23:37,120
into the nose

627
00:23:40,549 --> 00:23:39,200
and avaps which that was the drop sun

628
00:23:41,510 --> 00:23:40,559
system they'll be loading that into the

629
00:23:42,950 --> 00:23:41,520
tail

630
00:23:45,270 --> 00:23:42,960
so you can watch that while i tell you a

631
00:23:47,029 --> 00:23:45,280
little bit about how we do a mission so

632
00:23:48,710 --> 00:23:47,039
for example when the instruments first

633
00:23:49,669 --> 00:23:48,720
arrive the first thing we do is we weigh

634
00:23:53,350 --> 00:23:49,679
them

635
00:23:54,470 --> 00:23:53,360
computer that's going to communicate and

636
00:23:55,830 --> 00:23:54,480
find out

637
00:23:57,110 --> 00:23:55,840
if the instrument is properly

638
00:23:58,630 --> 00:23:57,120
communicating because we want to have

639
00:23:59,830 --> 00:23:58,640
the status of the of the instruments

640
00:24:01,990 --> 00:23:59,840
while they're flying we want it to be

641
00:24:04,070 --> 00:24:02,000
able to talk to us on the ground

642
00:24:05,270 --> 00:24:04,080
we also want to plug it in and see what

643
00:24:06,870 --> 00:24:05,280
kind of power

644
00:24:08,549 --> 00:24:06,880
uh it's going to draw so we want to have

645
00:24:10,870 --> 00:24:08,559
a very good characterization

646
00:24:12,149 --> 00:24:10,880
characterization of the plane of the

647
00:24:14,549 --> 00:24:12,159
instruments before we put them on the

648
00:24:16,230 --> 00:24:14,559
plane so once we've done that with all

649
00:24:19,990 --> 00:24:16,240
the instruments we put them all on the

650
00:24:21,830 --> 00:24:20,000
plane we attach all the fairings

651
00:24:24,549 --> 00:24:21,840
get the whole plane ready as if it's

652
00:24:27,510 --> 00:24:24,559
going to fly then we weigh it

653
00:24:28,630 --> 00:24:27,520
that gives us the center of gravity

654
00:24:33,909 --> 00:24:28,640
for

655
00:24:35,350 --> 00:24:33,919
fuel load after that we um

656
00:24:37,350 --> 00:24:35,360
we're getting ready for communication

657
00:24:39,750 --> 00:24:37,360
testing so what we want to do at that

658
00:24:42,230 --> 00:24:39,760
point is make sure that the scientists

659
00:24:44,470 --> 00:24:42,240
who will be at the facility the

660
00:24:45,909 --> 00:24:44,480
operations facility at wallops

661
00:24:47,350 --> 00:24:45,919
they'll be able to talk to their

662
00:24:50,070 --> 00:24:47,360
instruments and the instruments at that

663
00:24:52,070 --> 00:24:50,080
time are on the plane on the ground at

664
00:24:53,350 --> 00:24:52,080
dryden so that's our first test

665
00:24:54,870 --> 00:24:53,360
then we do a series of other

666
00:24:56,630 --> 00:24:54,880
communication tests to make sure

667
00:24:58,149 --> 00:24:56,640
everything's going to run when we're

668
00:24:59,909 --> 00:24:58,159
very confident that everything is

669
00:25:01,909 --> 00:24:59,919
communicating whether it be a science

670
00:25:04,230 --> 00:25:01,919
instrument or a facility instrument

671
00:25:05,909 --> 00:25:04,240
which would be things like a camera or

672
00:25:07,269 --> 00:25:05,919
the basic communication system for the

673
00:25:09,110 --> 00:25:07,279
plane

674
00:25:11,430 --> 00:25:09,120
no once all that is working

675
00:25:14,390 --> 00:25:11,440
then we're ready for a test flight so at

676
00:25:17,269 --> 00:25:14,400
that point we fly the plane in the area

677
00:25:18,549 --> 00:25:17,279
right around dryden to make sure that

678
00:25:21,110 --> 00:25:18,559
all the instruments are working well

679
00:25:22,470 --> 00:25:21,120
communicate well they fly for about five

680
00:25:25,830 --> 00:25:22,480
hours

681
00:25:28,950 --> 00:25:25,840
and at that point they um

682
00:25:32,630 --> 00:25:28,960
were ready for a transit flight so

683
00:25:34,710 --> 00:25:32,640
we are at that at that point um

684
00:25:37,510 --> 00:25:34,720
we're not quite at that point yet we're

685
00:25:39,830 --> 00:25:37,520
right now for hs3 2013

686
00:25:42,310 --> 00:25:39,840
we have

687
00:25:43,990 --> 00:25:42,320
sorry i keep seeing rob so i'm i'm

688
00:25:45,990 --> 00:25:44,000
distracted i'm not seeing the video

689
00:25:48,950 --> 00:25:46,000
sorry rob

690
00:25:51,350 --> 00:25:48,960
so that's better um anyway no offense

691
00:25:52,870 --> 00:25:51,360
rob but anyway the uh so when we transit

692
00:25:54,149 --> 00:25:52,880
the airplane

693
00:25:56,310 --> 00:25:54,159
and we'll do that the week of august

694
00:25:58,390 --> 00:25:56,320
second we'll transit both the airplanes

695
00:25:59,830 --> 00:25:58,400
right now in the process of that what i

696
00:26:01,190 --> 00:25:59,840
described to you we are at the point

697
00:26:02,870 --> 00:26:01,200
where the instruments have all been

698
00:26:04,630 --> 00:26:02,880
loaded on the plane

699
00:26:06,390 --> 00:26:04,640
we've done weight and balance and we've

700
00:26:08,390 --> 00:26:06,400
done the beginning of the communications

701
00:26:10,070 --> 00:26:08,400
test so soon we'll be ready for the

702
00:26:11,590 --> 00:26:10,080
range test and then we'll start planning

703
00:26:13,269 --> 00:26:11,600
our transit

704
00:26:15,029 --> 00:26:13,279
so this whole operation is very

705
00:26:16,950 --> 00:26:15,039
complicated there's a very large

706
00:26:18,789 --> 00:26:16,960
infrastructure at dryden for supporting

707
00:26:20,950 --> 00:26:18,799
the airplane but as you can imagine we

708
00:26:23,510 --> 00:26:20,960
have to do the same thing at wallops so

709
00:26:25,669 --> 00:26:23,520
we work with our colleagues here to be

710
00:26:27,669 --> 00:26:25,679
sure we have a hangar we have the proper

711
00:26:29,750 --> 00:26:27,679
fuel we have the proper ground support

712
00:26:31,669 --> 00:26:29,760
equipment tom was talking about in the

713
00:26:34,549 --> 00:26:31,679
plane taking off on the runway we have

714
00:26:35,909 --> 00:26:34,559
to realize since there isn't a pilot the

715
00:26:38,149 --> 00:26:35,919
pilot can't see if there is an

716
00:26:40,630 --> 00:26:38,159
obstruction on the runway for any reason

717
00:26:42,470 --> 00:26:40,640
so we have a a truck that goes alongside

718
00:26:44,230 --> 00:26:42,480
the plane when it's on the runway to be

719
00:26:46,149 --> 00:26:44,240
sure that there's no obstructions before

720
00:26:49,190 --> 00:26:46,159
it takes off so all those things have to

721
00:26:52,710 --> 00:26:49,200
be coordinated we have um space for the

722
00:26:54,310 --> 00:26:52,720
scientists space for the

723
00:26:56,310 --> 00:26:54,320
all the different instruments we have

724
00:26:58,310 --> 00:26:56,320
labs for them

725
00:27:00,230 --> 00:26:58,320
we have so many people involved it is

726
00:27:01,669 --> 00:27:00,240
very complex to set it all up we need to

727
00:27:02,630 --> 00:27:01,679
get them badged we need to make sure

728
00:27:04,070 --> 00:27:02,640
they all

729
00:27:07,430 --> 00:27:04,080
know how to work safely around the

730
00:27:10,070 --> 00:27:07,440
airplane we lay out an evacuation plan

731
00:27:11,669 --> 00:27:10,080
way in advance so that we're in case a

732
00:27:14,870 --> 00:27:11,679
storm comes our way we know how to get

733
00:27:16,230 --> 00:27:14,880
the planes and the people out safely

734
00:27:17,190 --> 00:27:16,240
all that is involved in the initial

735
00:27:18,549 --> 00:27:17,200
planning

736
00:27:20,470 --> 00:27:18,559
then we get ready to actually plan a

737
00:27:23,269 --> 00:27:20,480
particular flight

738
00:27:24,950 --> 00:27:23,279
so scott's told you about our goals well

739
00:27:26,870 --> 00:27:24,960
we have the goals then we have what the

740
00:27:29,269 --> 00:27:26,880
nature has put out as our targets do we

741
00:27:31,350 --> 00:27:29,279
have a storm out there that's going to

742
00:27:32,870 --> 00:27:31,360
it looks like it's developing do we have

743
00:27:35,110 --> 00:27:32,880
one that looks like it's going to

744
00:27:36,710 --> 00:27:35,120
intensify which one's closer which one

745
00:27:40,870 --> 00:27:36,720
should we choose

746
00:27:42,549 --> 00:27:40,880
and we have to do this 48 hours in

747
00:27:44,310 --> 00:27:42,559
advance we have to have a flight plan so

748
00:27:46,789 --> 00:27:44,320
we have to think about what we want to

749
00:27:49,190 --> 00:27:46,799
do and do we want to fly with those

750
00:27:51,510 --> 00:27:49,200
other groups the the noaa and air force

751
00:27:54,389 --> 00:27:51,520
aircraft that scott mentioned do we want

752
00:27:55,909 --> 00:27:54,399
to have them in the storm while we're

753
00:27:58,389 --> 00:27:55,919
going back and getting another plane how

754
00:27:59,830 --> 00:27:58,399
do we want to do it and we talk to them

755
00:28:02,149 --> 00:27:59,840
to the whole group once a week every

756
00:28:05,110 --> 00:28:02,159
once in once a day to look at our

757
00:28:07,029 --> 00:28:05,120
planning to see what we want to do

758
00:28:23,110 --> 00:28:07,039
all those things have to come together

759
00:28:31,029 --> 00:28:24,789
hey rob i think we lost her feed from

760
00:28:35,350 --> 00:28:32,710
okay it uh it looks like we may have

761
00:28:37,990 --> 00:28:35,360
lost uh maryland um we're getting a lot

762
00:28:40,149 --> 00:28:38,000
of great questions um which we will

763
00:28:43,110 --> 00:28:40,159
begin to address uh first i would like

764
00:28:45,190 --> 00:28:43,120
to go over to our guest

765
00:28:47,110 --> 00:28:45,200
uh brian mcnulty he's a senior research

766
00:28:48,789 --> 00:28:47,120
associate at the university of miami's

767
00:28:51,110 --> 00:28:48,799
rosenstein school of marine and

768
00:28:53,190 --> 00:28:51,120
atmospheric sciences in miami he's a

769
00:28:55,269 --> 00:28:53,200
tropical weather expert too for the

770
00:28:56,789 --> 00:28:55,279
washington post's capital weather gang

771
00:28:58,630 --> 00:28:56,799
blog

772
00:29:00,230 --> 00:28:58,640
some cool things about brian is that he

773
00:29:02,230 --> 00:29:00,240
actually spent a summer here at nasa

774
00:29:05,430 --> 00:29:02,240
goddard in 1997 so he gets to see the

775
00:29:08,149 --> 00:29:05,440
trim spacecraft and meet one of his um

776
00:29:09,510 --> 00:29:08,159
his his role models joanne simpson who

777
00:29:11,990 --> 00:29:09,520
he calls the mother of tropical

778
00:29:13,669 --> 00:29:12,000
meteorology

779
00:29:16,389 --> 00:29:13,679
he's most of his current research is on

780
00:29:19,510 --> 00:29:16,399
vortex initialization in models

781
00:29:22,149 --> 00:29:19,520
and it's about an analyzing a model and

782
00:29:24,789 --> 00:29:22,159
creating a new vortex that hopefully

783
00:29:26,470 --> 00:29:24,799
more closely resembles nature so brian

784
00:29:28,310 --> 00:29:26,480
why don't we just jump over to you and

785
00:29:29,510 --> 00:29:28,320
see if you have any questions for the

786
00:29:30,870 --> 00:29:29,520
panel

787
00:29:32,710 --> 00:29:30,880
and go from there

788
00:29:35,669 --> 00:29:32,720
all right thanks rob i appreciate the

789
00:29:37,110 --> 00:29:35,679
invitation to be on here with with uh

790
00:29:38,830 --> 00:29:37,120
the experts

791
00:29:41,669 --> 00:29:38,840
from hs 3

792
00:29:44,310 --> 00:29:41,679
program um

793
00:29:46,389 --> 00:29:44,320
yeah uh the the work being done by this

794
00:29:48,389 --> 00:29:46,399
is incredible um

795
00:29:51,190 --> 00:29:48,399
being able to

796
00:29:53,430 --> 00:29:51,200
to go out to the far eastern atlantic

797
00:29:55,990 --> 00:29:53,440
and look at storms is certainly a unique

798
00:29:58,230 --> 00:29:56,000
opportunity uh the manda aircraft at

799
00:30:00,710 --> 00:29:58,240
best can get out to

800
00:30:02,549 --> 00:30:00,720
um about the mid-atlantic and and that's

801
00:30:04,710 --> 00:30:02,559
a that's a stretch

802
00:30:06,070 --> 00:30:04,720
so this is this is really an incredible

803
00:30:07,190 --> 00:30:06,080
opportunity

804
00:30:09,590 --> 00:30:07,200
and uh

805
00:30:11,350 --> 00:30:09,600
it's it's really great to see

806
00:30:12,470 --> 00:30:11,360
that we have you know year after year of

807
00:30:13,269 --> 00:30:12,480
this so

808
00:30:16,389 --> 00:30:13,279
um

809
00:30:18,310 --> 00:30:16,399
so we'll see what sort of storms we can

810
00:30:19,190 --> 00:30:18,320
get this year

811
00:30:20,789 --> 00:30:19,200
um

812
00:30:23,830 --> 00:30:20,799
as far as

813
00:30:26,789 --> 00:30:23,840
questions go i guess maybe my first one

814
00:30:29,590 --> 00:30:26,799
would be uh for

815
00:30:33,110 --> 00:30:29,600
tom um

816
00:30:34,230 --> 00:30:33,120
now you've mentioned we can fly

817
00:30:42,710 --> 00:30:34,240
we can fly

818
00:30:44,230 --> 00:30:42,720
a time and

819
00:30:48,230 --> 00:30:44,240
those can be

820
00:30:49,990 --> 00:30:48,240
in coordination with either a noaa or a

821
00:30:51,430 --> 00:30:50,000
an air force plane so they could be

822
00:30:53,830 --> 00:30:51,440
flying through the same

823
00:30:55,750 --> 00:30:53,840
storm or on top of the same storm at the

824
00:30:58,149 --> 00:30:55,760
same time

825
00:30:59,750 --> 00:30:58,159
yeah that's true uh however uh remember

826
00:31:01,990 --> 00:30:59,760
these aircraft are typically going to be

827
00:31:05,510 --> 00:31:02,000
at different altitudes obviously we're

828
00:31:07,190 --> 00:31:05,520
the high flyers out there and then

829
00:31:09,590 --> 00:31:07,200
the other aircraft will be in there but

830
00:31:11,269 --> 00:31:09,600
we do have a pretty um

831
00:31:13,029 --> 00:31:11,279
good communications plan this is

832
00:31:14,549 --> 00:31:13,039
something we've been working on for a

833
00:31:16,789 --> 00:31:14,559
long time in fact it's been years in

834
00:31:18,789 --> 00:31:16,799
development

835
00:31:21,430 --> 00:31:18,799
nasa and noaa have been doing hurricane

836
00:31:23,430 --> 00:31:21,440
research for a long time so uh that's

837
00:31:25,830 --> 00:31:23,440
key as marilyn said is the coordination

838
00:31:28,870 --> 00:31:25,840
between all the external agencies

839
00:31:47,430 --> 00:31:28,880
so we have this plan that we use and

840
00:31:51,669 --> 00:31:49,110
network kicked me off there for a second

841
00:31:54,710 --> 00:31:51,679
so okay no problem

842
00:31:56,149 --> 00:31:54,720
so we uh uh follow this plan pretty uh

843
00:31:58,149 --> 00:31:56,159
pretty closely to make sure that

844
00:31:59,990 --> 00:31:58,159
everybody is uh um

845
00:32:02,310 --> 00:32:00,000
not in the same airspace at the same

846
00:32:04,389 --> 00:32:02,320
time and we're not dropping things

847
00:32:07,350 --> 00:32:04,399
in a place where we won't want to draw

848
00:32:09,029 --> 00:32:07,360
so right that that's the key here and uh

849
00:32:11,269 --> 00:32:09,039
you know maryland does a really good job

850
00:32:17,110 --> 00:32:11,279
of corralling everybody together and

851
00:32:20,630 --> 00:32:19,269
terrific so yeah i guess i mean one

852
00:32:22,710 --> 00:32:20,640
thing that just

853
00:32:25,269 --> 00:32:22,720
if anyone

854
00:32:26,830 --> 00:32:25,279
is curious if these these planes don't

855
00:32:29,269 --> 00:32:26,840
replace what we have now in terms of

856
00:32:31,509 --> 00:32:29,279
demand missions that fly right into the

857
00:32:34,149 --> 00:32:31,519
eye of a hurricane and measure the

858
00:32:36,070 --> 00:32:34,159
maximum winds and all that so these are

859
00:32:37,590 --> 00:32:36,080
just kind of a really great extra

860
00:32:39,350 --> 00:32:37,600
resource

861
00:32:41,190 --> 00:32:39,360
um to

862
00:32:42,549 --> 00:32:41,200
go ahead yeah that's that's true brian

863
00:32:45,509 --> 00:32:42,559
and that's really the same for any

864
00:32:47,990 --> 00:32:45,519
aircraft all aircraft are uh are good at

865
00:32:49,750 --> 00:32:48,000
doing certain things and really the key

866
00:32:52,710 --> 00:32:49,760
is combining all of these aircraft

867
00:32:53,990 --> 00:32:52,720
together and uh using the advantages of

868
00:32:57,029 --> 00:32:54,000
each of them it provides a lot of

869
00:32:58,870 --> 00:32:57,039
synergy for the whole project as a whole

870
00:33:00,789 --> 00:32:58,880
absolutely yeah it's wonderful and being

871
00:33:03,509 --> 00:33:00,799
able to go out and get the

872
00:33:04,789 --> 00:33:03,519
wind fields from storms in the far east

873
00:33:07,029 --> 00:33:04,799
eastern atlantic is something we've

874
00:33:08,389 --> 00:33:07,039
never been able to do

875
00:33:12,389 --> 00:33:08,399
um

876
00:33:15,669 --> 00:33:12,399
and then again the the big push on

877
00:33:16,789 --> 00:33:15,679
being able to to understand the uh dry

878
00:33:19,350 --> 00:33:16,799
air

879
00:33:21,830 --> 00:33:19,360
coming off of africa the these saharan

880
00:33:24,389 --> 00:33:21,840
air layers is a huge mystery

881
00:33:25,990 --> 00:33:24,399
um what what impact that has on

882
00:33:29,990 --> 00:33:26,000
hurricane

883
00:33:30,950 --> 00:33:30,000
or if they strengthen at all

884
00:33:32,549 --> 00:33:30,960
um

885
00:33:34,310 --> 00:33:32,559
there's some

886
00:33:35,750 --> 00:33:34,320
some proof that

887
00:33:37,350 --> 00:33:35,760
that the

888
00:33:38,710 --> 00:33:37,360
saharan air layer can actually help

889
00:33:40,549 --> 00:33:38,720
storms and

890
00:33:42,470 --> 00:33:40,559
some on the flip side that it's not so

891
00:33:43,750 --> 00:33:42,480
good for them

892
00:33:44,789 --> 00:33:43,760
um

893
00:33:45,750 --> 00:33:44,799
so

894
00:33:47,590 --> 00:33:45,760
um

895
00:33:49,750 --> 00:33:47,600
maybe a question then for

896
00:33:53,909 --> 00:33:49,760
scott would be what happens to these

897
00:33:55,750 --> 00:33:53,919
instruments after hs3 is over

898
00:33:57,029 --> 00:33:55,760
obviously there's some great instruments

899
00:33:57,909 --> 00:33:57,039
at work here

900
00:33:59,830 --> 00:33:57,919
um

901
00:34:01,830 --> 00:33:59,840
do they just get retired or what's their

902
00:34:04,470 --> 00:34:01,840
future

903
00:34:07,350 --> 00:34:04,480
uh no they won't be retired uh all these

904
00:34:08,310 --> 00:34:07,360
instruments are generally funded uh

905
00:34:10,470 --> 00:34:08,320
through

906
00:34:13,270 --> 00:34:10,480
various research programs so right now

907
00:34:14,389 --> 00:34:13,280
they're committed to hs3 for three years

908
00:34:16,069 --> 00:34:14,399
of flights

909
00:34:17,190 --> 00:34:16,079
when this is done

910
00:34:18,149 --> 00:34:17,200
they'll

911
00:34:19,829 --> 00:34:18,159
likely

912
00:34:22,389 --> 00:34:19,839
be trying to get funding for additional

913
00:34:23,270 --> 00:34:22,399
support for other campaigns for example

914
00:34:25,430 --> 00:34:23,280
uh

915
00:34:28,470 --> 00:34:25,440
hsc was funded under the first round of

916
00:34:31,190 --> 00:34:28,480
nasa's earth venture suborbital call uh

917
00:34:33,589 --> 00:34:31,200
back in 2009 and right now they're going

918
00:34:35,750 --> 00:34:33,599
through the process of select of getting

919
00:34:37,589 --> 00:34:35,760
uh new proposals and next year they'll

920
00:34:38,790 --> 00:34:37,599
make selections for a new round and so

921
00:34:40,790 --> 00:34:38,800
it's possible that some of these

922
00:34:43,349 --> 00:34:40,800
instruments will get funded for other

923
00:34:45,829 --> 00:34:43,359
projects whether it's hurricanes uh

924
00:34:47,270 --> 00:34:45,839
winter storms uh maybe more climate and

925
00:34:48,790 --> 00:34:47,280
chemistry well these wouldn't be

926
00:34:49,909 --> 00:34:48,800
necessary for climate chemistry some of

927
00:34:52,790 --> 00:34:49,919
them might be

928
00:34:55,190 --> 00:34:52,800
um but basically they're

929
00:34:55,990 --> 00:34:55,200
tied to opportunities for funding

930
00:34:57,589 --> 00:34:56,000
uh

931
00:34:59,349 --> 00:34:57,599
and so it's kind of hard to say what

932
00:35:00,790 --> 00:34:59,359
will happen next for a lot of these

933
00:35:02,390 --> 00:35:00,800
instruments other than that they'll

934
00:35:04,230 --> 00:35:02,400
eventually find their way into another

935
00:35:06,470 --> 00:35:04,240
project somewhere

936
00:35:07,589 --> 00:35:06,480
all right and speaking of that um is

937
00:35:10,390 --> 00:35:07,599
there

938
00:35:12,470 --> 00:35:10,400
uh

939
00:35:13,270 --> 00:35:12,480
have you guys kind of put on the wish

940
00:35:15,109 --> 00:35:13,280
list

941
00:35:16,710 --> 00:35:15,119
being able to have a global hawk in the

942
00:35:18,870 --> 00:35:16,720
long term for

943
00:35:21,030 --> 00:35:18,880
hurricane recon

944
00:35:22,790 --> 00:35:21,040
uh well with nasa with hs3 you know

945
00:35:25,030 --> 00:35:22,800
again it's only funded for the five

946
00:35:29,270 --> 00:35:25,040
years and there's no real plan for for

947
00:35:31,510 --> 00:35:29,280
the long term uh within nasa as regular

948
00:35:32,790 --> 00:35:31,520
reconnaissance since we do more or more

949
00:35:35,349 --> 00:35:32,800
research oriented rather than

950
00:35:37,510 --> 00:35:35,359
operational uh operationally oriented

951
00:35:39,910 --> 00:35:37,520
however we are having some discussions

952
00:35:42,230 --> 00:35:39,920
with noaa noaa has a a very deep

953
00:35:44,230 --> 00:35:42,240
interest in using the aircraft for both

954
00:35:45,990 --> 00:35:44,240
hurricanes and winter storms and there

955
00:35:47,670 --> 00:35:46,000
are some discussions at high levels

956
00:35:48,870 --> 00:35:47,680
about trying to

957
00:35:50,310 --> 00:35:48,880
um

958
00:35:53,030 --> 00:35:50,320
make the earth want at least one of the

959
00:35:54,790 --> 00:35:53,040
aircraft or maybe both available to noaa

960
00:35:56,230 --> 00:35:54,800
uh contingent upon

961
00:35:59,349 --> 00:35:56,240
being able to work out the some of the

962
00:36:01,030 --> 00:35:59,359
funding issues terrific

963
00:36:03,510 --> 00:36:01,040
all right i think that's

964
00:36:05,430 --> 00:36:03,520
that's my main questions right now

965
00:36:07,430 --> 00:36:05,440
thank you guys all right thank you brian

966
00:36:10,550 --> 00:36:07,440
uh we have uh quite a number of reporter

967
00:36:12,950 --> 00:36:10,560
questions um and questions from google

968
00:36:15,510 --> 00:36:12,960
youtube and twitter um the first

969
00:36:17,430 --> 00:36:15,520
question is from carrie rose and carrie

970
00:36:19,109 --> 00:36:17,440
has addressed to scott

971
00:36:20,950 --> 00:36:19,119
scott she would like to know she would

972
00:36:22,710 --> 00:36:20,960
like you to restate which piggyback

973
00:36:25,109 --> 00:36:22,720
instrument is being added to the

974
00:36:27,030 --> 00:36:25,119
overstorm aircraft

975
00:36:29,349 --> 00:36:27,040
well the acronym for the instrument is

976
00:36:31,670 --> 00:36:29,359
the dell a-d-e-l-e

977
00:36:33,910 --> 00:36:31,680
uh i can't off the top of my head

978
00:36:35,990 --> 00:36:33,920
remember what the acronym stands for but

979
00:36:38,390 --> 00:36:36,000
it's a gamma-ray uh

980
00:36:39,990 --> 00:36:38,400
detector so basically it's looking for

981
00:36:42,069 --> 00:36:40,000
gamma rays that are emitted from

982
00:36:43,589 --> 00:36:42,079
lightning at the top of the storm uh

983
00:36:46,790 --> 00:36:43,599
well the gamma rays are emitted from the

984
00:36:48,470 --> 00:36:46,800
top of the storm um and so they're

985
00:36:49,990 --> 00:36:48,480
they're they're relatively rare events

986
00:36:51,670 --> 00:36:50,000
but this is an opportunity for them to

987
00:36:53,430 --> 00:36:51,680
get on a high altitude aircraft where

988
00:36:56,069 --> 00:36:53,440
they might be readily able to see these

989
00:36:57,670 --> 00:36:56,079
types of phenomena

990
00:37:00,870 --> 00:36:57,680
and adele is not named after the pop

991
00:37:02,470 --> 00:37:00,880
singer who's saying sky fall by the way

992
00:37:04,710 --> 00:37:02,480
um and by the way we're getting a lot of

993
00:37:07,270 --> 00:37:04,720
questions about whether or not uh hs3

994
00:37:08,790 --> 00:37:07,280
will see a sharknado and the answer to

995
00:37:10,550 --> 00:37:08,800
that is no

996
00:37:12,069 --> 00:37:10,560
so for everybody who sent out that

997
00:37:14,069 --> 00:37:12,079
question though we could just move on

998
00:37:16,150 --> 00:37:14,079
from there no sharknados occur on too

999
00:37:18,310 --> 00:37:16,160
small of a scale

1000
00:37:20,829 --> 00:37:18,320
thank you scott

1001
00:37:23,030 --> 00:37:20,839
uh another uh reported question

1002
00:37:26,069 --> 00:37:23,040
um this question

1003
00:37:28,150 --> 00:37:26,079
is how do the instruments on hs3 compare

1004
00:37:31,190 --> 00:37:28,160
to the instruments that are already in

1005
00:37:34,069 --> 00:37:31,200
use by satellites

1006
00:37:36,069 --> 00:37:34,079
uh well some of the instruments are are

1007
00:37:38,069 --> 00:37:36,079
similar in some ways to what's on

1008
00:37:39,910 --> 00:37:38,079
satellites uh the scanning his

1009
00:37:42,310 --> 00:37:39,920
instrument is very similar to the ayers

1010
00:37:43,589 --> 00:37:42,320
instrument that's on the aqua satellite

1011
00:37:44,950 --> 00:37:43,599
um

1012
00:37:47,589 --> 00:37:44,960
which basically gives you temperature

1013
00:37:49,030 --> 00:37:47,599
and humidity profiles uh the cloud

1014
00:37:50,390 --> 00:37:49,040
physics lidar and the nose of the

1015
00:37:52,550 --> 00:37:50,400
environmental aircraft

1016
00:37:54,310 --> 00:37:52,560
uh is basically the same type of

1017
00:37:55,990 --> 00:37:54,320
measurement as we get from a satellite

1018
00:37:59,589 --> 00:37:56,000
called calypso

1019
00:38:00,710 --> 00:37:59,599
that gives profiles and dust and clouds

1020
00:38:03,829 --> 00:38:00,720
um

1021
00:38:06,870 --> 00:38:03,839
in terms of the overstorm aircraft the

1022
00:38:08,470 --> 00:38:06,880
doppler radar is is sort of an advanced

1023
00:38:10,230 --> 00:38:08,480
version of something that we'll see

1024
00:38:12,550 --> 00:38:10,240
right now with our tropical rainfall

1025
00:38:14,790 --> 00:38:12,560
measuring mission uh satellite that's

1026
00:38:17,190 --> 00:38:14,800
been going for about more than 15 years

1027
00:38:20,950 --> 00:38:17,200
now it has the first and only

1028
00:38:22,390 --> 00:38:20,960
rain or precipitation radar in space

1029
00:38:24,310 --> 00:38:22,400
but it's there's going to be a follow-on

1030
00:38:25,750 --> 00:38:24,320
mission that launches next february

1031
00:38:27,670 --> 00:38:25,760
called the global precipitation

1032
00:38:29,670 --> 00:38:27,680
measurement mission which will be a dual

1033
00:38:31,990 --> 00:38:29,680
frequency radar

1034
00:38:34,150 --> 00:38:32,000
just getting precipitation profiles not

1035
00:38:36,230 --> 00:38:34,160
wind information from space but the two

1036
00:38:37,990 --> 00:38:36,240
frequencies on the gpm satellite are

1037
00:38:40,470 --> 00:38:38,000
identical to what we have on the high

1038
00:38:41,990 --> 00:38:40,480
rep doppler radar

1039
00:38:46,230 --> 00:38:42,000
the

1040
00:38:49,670 --> 00:38:46,240
and don't really necessarily have a

1041
00:38:51,589 --> 00:38:49,680
space equivalent at this point

1042
00:38:54,470 --> 00:38:51,599
thank you scott um there are a couple

1043
00:38:55,510 --> 00:38:54,480
more couple of questions from fiona

1044
00:38:57,990 --> 00:38:55,520
tall

1045
00:39:00,310 --> 00:38:58,000
one question is it is it possible to

1046
00:39:01,349 --> 00:39:00,320
access the data about hurricane nadine

1047
00:39:02,790 --> 00:39:01,359
um

1048
00:39:05,589 --> 00:39:02,800
from

1049
00:39:07,670 --> 00:39:05,599
a non-hs3 perspective or actually even

1050
00:39:09,510 --> 00:39:07,680
including an hs3 perspective you can

1051
00:39:12,790 --> 00:39:09,520
find nadine under the nasa hurricane

1052
00:39:15,990 --> 00:39:12,800
page archives at nasa.gov hurricane in

1053
00:39:17,510 --> 00:39:16,000
the 2012 list of storms where we do have

1054
00:39:18,470 --> 00:39:17,520
a lot of the different nasa satellite

1055
00:39:20,870 --> 00:39:18,480
data

1056
00:39:22,550 --> 00:39:20,880
as well as some of the information from

1057
00:39:24,950 --> 00:39:22,560
when hs3

1058
00:39:26,150 --> 00:39:24,960
sent the global hawks over it

1059
00:39:29,750 --> 00:39:26,160
scott would you like to follow up with

1060
00:39:31,589 --> 00:39:29,760
that uh yeah all the data is made uh

1061
00:39:34,069 --> 00:39:31,599
freely available to the public uh

1062
00:39:37,349 --> 00:39:34,079
anybody who wants to use it uh if people

1063
00:39:38,310 --> 00:39:37,359
go to our project web page

1064
00:39:41,349 --> 00:39:38,320
which is

1065
00:39:47,030 --> 00:39:44,710
hs3 there's a link on the left side that

1066
00:39:49,910 --> 00:39:47,040
is for data and and we it basically

1067
00:39:52,470 --> 00:39:49,920
links you to archived web pages for each

1068
00:39:54,390 --> 00:39:52,480
of the instruments uh that have that

1069
00:39:55,829 --> 00:39:54,400
flew on the environmental aircraft last

1070
00:39:57,109 --> 00:39:55,839
year

1071
00:39:59,190 --> 00:39:57,119
of course it takes some level of

1072
00:40:00,710 --> 00:39:59,200
expertise to learn how to use these data

1073
00:40:02,310 --> 00:40:00,720
sets but for any researchers in

1074
00:40:04,230 --> 00:40:02,320
particular who are interested in using

1075
00:40:06,470 --> 00:40:04,240
these data they can just go to those

1076
00:40:08,150 --> 00:40:06,480
websites and and download the data and

1077
00:40:10,390 --> 00:40:08,160
start working with them

1078
00:40:12,230 --> 00:40:10,400
typically after data is collected while

1079
00:40:14,630 --> 00:40:12,240
we're in the field there's a period of

1080
00:40:17,430 --> 00:40:14,640
about six months where

1081
00:40:19,349 --> 00:40:17,440
the data is processed quality controlled

1082
00:40:21,670 --> 00:40:19,359
and then once we make sure everything is

1083
00:40:23,910 --> 00:40:21,680
all right then we we put the link on the

1084
00:40:26,150 --> 00:40:23,920
web page so that it becomes available to

1085
00:40:28,310 --> 00:40:26,160
anybody who wants to use it

1086
00:40:29,670 --> 00:40:28,320
okay

1087
00:40:32,710 --> 00:40:29,680
thank you scott

1088
00:40:36,390 --> 00:40:32,720
um the next question is about education

1089
00:40:38,230 --> 00:40:36,400
materials on hs3 and hurricanes for

1090
00:40:39,589 --> 00:40:38,240
education materials on hurricanes in

1091
00:40:42,310 --> 00:40:39,599
general you can also go back to the

1092
00:40:44,550 --> 00:40:42,320
national arcane page nasa.gov hurricane

1093
00:40:46,390 --> 00:40:44,560
there is an educators section there

1094
00:40:50,470 --> 00:40:46,400
i'm going to throw it to maryland

1095
00:40:53,430 --> 00:40:50,480
vasquez about the hs3

1096
00:40:56,550 --> 00:40:53,440
yes thank you i'm glad to be back um

1097
00:40:58,230 --> 00:40:56,560
the we do have uh materials uh there's

1098
00:41:00,550 --> 00:40:58,240
in for information on our website that

1099
00:41:03,030 --> 00:41:00,560
scott talked about um i think that's the

1100
00:41:04,230 --> 00:41:03,040
best place we also have links to

1101
00:41:06,309 --> 00:41:04,240
information

1102
00:41:09,750 --> 00:41:06,319
in our calendar about events that have

1103
00:41:11,349 --> 00:41:09,760
to do with epo or public affairs so i

1104
00:41:14,309 --> 00:41:11,359
would say the best place to start is our

1105
00:41:17,589 --> 00:41:16,069
thank you marilyn

1106
00:41:20,309 --> 00:41:17,599
uh we have a question from seth

1107
00:41:22,390 --> 00:41:20,319
bornstein of associated press and this

1108
00:41:24,630 --> 00:41:22,400
one involves operational data will the

1109
00:41:26,470 --> 00:41:24,640
national hurricane center forecasters be

1110
00:41:29,430 --> 00:41:26,480
able to use any of the data for their

1111
00:41:32,950 --> 00:41:31,510
all right well um from the environmental

1112
00:41:34,470 --> 00:41:32,960
aircraft

1113
00:41:36,550 --> 00:41:34,480
the drops on data

1114
00:41:37,990 --> 00:41:36,560
does get used it's it's processed in

1115
00:41:40,630 --> 00:41:38,000
real time

1116
00:41:42,630 --> 00:41:40,640
by people at the noaa hurricane research

1117
00:41:45,270 --> 00:41:42,640
division and then they pass the

1118
00:41:46,950 --> 00:41:45,280
information uh on to the national

1119
00:41:48,390 --> 00:41:46,960
hurricane center

1120
00:41:51,030 --> 00:41:48,400
in addition the

1121
00:41:53,670 --> 00:41:51,040
data is uploaded to a global

1122
00:41:54,710 --> 00:41:53,680
uh system for sharing the data and it's

1123
00:41:56,550 --> 00:41:54,720
so it's available not only for the

1124
00:41:58,790 --> 00:41:56,560
hurricane center but for operational

1125
00:42:00,790 --> 00:41:58,800
forecast centers who might want to

1126
00:42:01,829 --> 00:42:00,800
ingest that data into the forecast

1127
00:42:03,589 --> 00:42:01,839
models

1128
00:42:05,670 --> 00:42:03,599
the other data such as from the cloud

1129
00:42:07,109 --> 00:42:05,680
physics lidar and scanning his

1130
00:42:09,910 --> 00:42:07,119
are not as

1131
00:42:11,190 --> 00:42:09,920
easy to use operationally

1132
00:42:13,270 --> 00:42:11,200
but we

1133
00:42:14,870 --> 00:42:13,280
can make some of the data available in

1134
00:42:16,870 --> 00:42:14,880
real time i think they're going to be

1135
00:42:19,270 --> 00:42:16,880
particularly interested in the data from

1136
00:42:21,030 --> 00:42:19,280
our overstorm aircraft and since this is

1137
00:42:23,430 --> 00:42:21,040
our first year of flying the overstorm

1138
00:42:25,270 --> 00:42:23,440
aircraft and the field

1139
00:42:25,990 --> 00:42:25,280
we have to see what we can do in terms

1140
00:42:28,390 --> 00:42:26,000
of

1141
00:42:31,589 --> 00:42:28,400
getting that data to them in real time

1142
00:42:33,349 --> 00:42:31,599
when you're trying to download uh large

1143
00:42:35,829 --> 00:42:33,359
data sets from an aircraft down to the

1144
00:42:37,349 --> 00:42:35,839
ground we're limited by bandwidth and

1145
00:42:40,309 --> 00:42:37,359
and it can be hard to get the

1146
00:42:41,670 --> 00:42:40,319
information down uh quickly uh and with

1147
00:42:44,390 --> 00:42:41,680
the sort of products that they want to

1148
00:42:45,510 --> 00:42:44,400
see so this year sort of a test for us

1149
00:42:47,670 --> 00:42:45,520
to to

1150
00:42:50,390 --> 00:42:47,680
uh produce certain types of products we

1151
00:42:52,069 --> 00:42:50,400
think would be useful for them

1152
00:42:53,829 --> 00:42:52,079
share that with them maybe not

1153
00:42:55,670 --> 00:42:53,839
necessarily in real time but shortly

1154
00:42:57,430 --> 00:42:55,680
after to get some feedback and then

1155
00:42:59,829 --> 00:42:57,440
hopefully by next year

1156
00:43:01,670 --> 00:42:59,839
we can try to get the data to them in

1157
00:43:04,069 --> 00:43:01,680
real time where it could help with their

1158
00:43:06,069 --> 00:43:04,079
forecast operations these are things

1159
00:43:07,589 --> 00:43:06,079
that we're not required to do but we

1160
00:43:09,670 --> 00:43:07,599
certainly try to do on a best effort

1161
00:43:11,750 --> 00:43:09,680
basis because we know that they will

1162
00:43:13,670 --> 00:43:11,760
that they can be beneficial and so we're

1163
00:43:15,990 --> 00:43:13,680
making every effort to do it but again

1164
00:43:18,870 --> 00:43:16,000
you need to keep in mind that this is a

1165
00:43:21,349 --> 00:43:18,880
a fairly complex operation a lot of

1166
00:43:23,109 --> 00:43:21,359
things being done for the first time and

1167
00:43:25,270 --> 00:43:23,119
there's some kinks to be worked out in

1168
00:43:27,430 --> 00:43:25,280
communicating such large data sets in

1169
00:43:28,790 --> 00:43:27,440
real time

1170
00:43:30,470 --> 00:43:28,800
all right thank you scott we have

1171
00:43:32,550 --> 00:43:30,480
another question from elizabeth harbaugh

1172
00:43:34,870 --> 00:43:32,560
she actually would like you to elaborate

1173
00:43:37,510 --> 00:43:34,880
on the saharan air layer

1174
00:43:41,270 --> 00:43:37,520
and why it may help hurricanes either

1175
00:43:43,349 --> 00:43:41,280
intensify or it may

1176
00:43:45,829 --> 00:43:43,359
help them fizzle out

1177
00:43:47,750 --> 00:43:45,839
okay well it helps to kind of keep in

1178
00:43:50,309 --> 00:43:47,760
mind certain things that that are needed

1179
00:43:52,069 --> 00:43:50,319
for hurricanes to form and grow

1180
00:43:54,390 --> 00:43:52,079
one you need to have

1181
00:43:56,790 --> 00:43:54,400
fairly humid air to foster cloud

1182
00:43:58,790 --> 00:43:56,800
development dry air tends to disrupt

1183
00:44:00,710 --> 00:43:58,800
cloud development and and even lead the

1184
00:44:02,470 --> 00:44:00,720
cooling down near the surface due to in

1185
00:44:03,990 --> 00:44:02,480
downdrafts

1186
00:44:06,230 --> 00:44:04,000
you also need the air to be fairly

1187
00:44:08,150 --> 00:44:06,240
unstable so where when it starts to rise

1188
00:44:09,829 --> 00:44:08,160
it wants to continue to rise to develop

1189
00:44:12,069 --> 00:44:09,839
a deep thunderstorm

1190
00:44:13,030 --> 00:44:12,079
whereas the air becomes stable it might

1191
00:44:15,589 --> 00:44:13,040
tend to

1192
00:44:16,790 --> 00:44:15,599
prevent that rising motion

1193
00:44:18,150 --> 00:44:16,800
and then also

1194
00:44:19,670 --> 00:44:18,160
hurricanes

1195
00:44:22,069 --> 00:44:19,680
and developing tropical storms don't

1196
00:44:25,109 --> 00:44:22,079
like what's called vertical wind shear

1197
00:44:27,510 --> 00:44:25,119
this is the change of winds with height

1198
00:44:29,109 --> 00:44:27,520
and that can have a shearing effect on

1199
00:44:31,109 --> 00:44:29,119
the storms and basically rip them apart

1200
00:44:32,790 --> 00:44:31,119
if the shear becomes too strong

1201
00:44:37,109 --> 00:44:32,800
so with the saharan air layer it's a

1202
00:44:39,190 --> 00:44:37,119
very hot dry dusty air mass and

1203
00:44:41,589 --> 00:44:39,200
in that layer itself

1204
00:44:42,950 --> 00:44:41,599
that hot air overrides cooler air near

1205
00:44:44,710 --> 00:44:42,960
the surface so it tends to be very

1206
00:44:47,109 --> 00:44:44,720
stable and it's hard to get deep cloud

1207
00:44:49,990 --> 00:44:47,119
development the dry air can potentially

1208
00:44:52,309 --> 00:44:50,000
mix into storms and kind of cause them

1209
00:44:54,710 --> 00:44:52,319
to lose some energy and then on the

1210
00:44:57,190 --> 00:44:54,720
southern side of the saharan air layer

1211
00:44:59,430 --> 00:44:57,200
there tends to be a strong mid-level

1212
00:45:01,030 --> 00:44:59,440
wind maximum or jet

1213
00:45:02,309 --> 00:45:01,040
that can increase the vertical wind

1214
00:45:04,230 --> 00:45:02,319
shear so those are some of the arguments

1215
00:45:06,230 --> 00:45:04,240
about why it may inhibit storm

1216
00:45:08,230 --> 00:45:06,240
development just through increasing

1217
00:45:10,150 --> 00:45:08,240
stability bringing dry air and

1218
00:45:13,270 --> 00:45:10,160
increasing vertical wind shear

1219
00:45:15,510 --> 00:45:13,280
now the arguments as for why it may have

1220
00:45:17,349 --> 00:45:15,520
a positive influence on growth is a

1221
00:45:19,109 --> 00:45:17,359
little bit more complex but it has to do

1222
00:45:21,990 --> 00:45:19,119
with the energetics of the large-scale

1223
00:45:23,750 --> 00:45:22,000
wave uh in which the storm is embedded

1224
00:45:26,550 --> 00:45:23,760
and basically the southern side of the

1225
00:45:28,710 --> 00:45:26,560
sow acts kind of like a front

1226
00:45:30,710 --> 00:45:28,720
and it may foster a vertical circulation

1227
00:45:32,950 --> 00:45:30,720
that leads to rising motion south of

1228
00:45:36,309 --> 00:45:32,960
that front which is where you would

1229
00:45:38,230 --> 00:45:36,319
typically get a tropical cloud formation

1230
00:45:41,349 --> 00:45:38,240
and so it may enhance that

1231
00:45:43,589 --> 00:45:41,359
in addition it may allow for conversions

1232
00:45:45,270 --> 00:45:43,599
of energy from the larger scale down to

1233
00:45:48,230 --> 00:45:45,280
the scale of the

1234
00:45:49,990 --> 00:45:48,240
developing hurricane

1235
00:45:53,109 --> 00:45:50,000
a sort of large-scale dynamical

1236
00:45:55,270 --> 00:45:53,119
instability that may favor growth

1237
00:45:56,550 --> 00:45:55,280
and it's a little bit hard to determine

1238
00:45:57,990 --> 00:45:56,560
at this point

1239
00:46:01,270 --> 00:45:58,000
whether the

1240
00:46:03,829 --> 00:46:01,280
positive influences outweigh uh the

1241
00:46:05,349 --> 00:46:03,839
negative influences or if it may vary

1242
00:46:06,630 --> 00:46:05,359
from case to case so that's one of the

1243
00:46:07,670 --> 00:46:06,640
things that we want to do is get some

1244
00:46:09,670 --> 00:46:07,680
data

1245
00:46:11,270 --> 00:46:09,680
on these storms these things

1246
00:46:12,950 --> 00:46:11,280
are most prominent out in the central

1247
00:46:15,430 --> 00:46:12,960
and eastern atlantic where we often

1248
00:46:17,990 --> 00:46:15,440
don't get uh much data so that's one of

1249
00:46:20,150 --> 00:46:18,000
the motivations for us is to get out to

1250
00:46:21,589 --> 00:46:20,160
these storms much earlier and look at

1251
00:46:23,270 --> 00:46:21,599
this interaction in a way that we

1252
00:46:27,430 --> 00:46:23,280
haven't been able to do

1253
00:46:31,589 --> 00:46:29,349
okay thank you scott um we have another

1254
00:46:34,150 --> 00:46:31,599
question um

1255
00:46:36,150 --> 00:46:34,160
about the drop songs the the question is

1256
00:46:37,430 --> 00:46:36,160
are the small cylindrical tube sensors

1257
00:46:39,829 --> 00:46:37,440
that you mentioned

1258
00:46:42,870 --> 00:46:39,839
able to be recovered or are they and

1259
00:46:44,710 --> 00:46:42,880
reused or are they single use only

1260
00:46:47,910 --> 00:46:44,720
no they're a single use only they're

1261
00:46:49,990 --> 00:46:47,920
basically falling uh to the surface uh

1262
00:46:52,309 --> 00:46:50,000
while they do have a gps sensor in it to

1263
00:46:54,470 --> 00:46:52,319
tell us their exact position

1264
00:46:56,309 --> 00:46:54,480
um i don't believe that they float or at

1265
00:46:58,069 --> 00:46:56,319
least not for long and they'd be pretty

1266
00:47:00,069 --> 00:46:58,079
difficult to recover so they're

1267
00:47:03,109 --> 00:47:00,079
basically expendables that are used once

1268
00:47:06,630 --> 00:47:04,470
i do think the national weather service

1269
00:47:08,950 --> 00:47:06,640
has a program where you can mail a drop

1270
00:47:12,309 --> 00:47:08,960
zone back though if it falls over land

1271
00:47:16,150 --> 00:47:12,319
somewhere but we're so far out at sea

1272
00:47:20,150 --> 00:47:18,550
thank you scott

1273
00:47:22,550 --> 00:47:20,160
let's see we have um

1274
00:47:24,309 --> 00:47:22,560
another question from twitter uh julie

1275
00:47:26,390 --> 00:47:24,319
bookman uh before i get to that just a

1276
00:47:28,550 --> 00:47:26,400
reminder we have about uh 12 minutes

1277
00:47:30,309 --> 00:47:28,560
left on the hangout if you have any

1278
00:47:33,589 --> 00:47:30,319
comments you can ask your comments

1279
00:47:35,349 --> 00:47:33,599
through youtube or twitter by hashtag

1280
00:47:37,349 --> 00:47:35,359
nasahs3

1281
00:47:38,550 --> 00:47:37,359
or you can ask them on the google plus

1282
00:47:39,510 --> 00:47:38,560
page

1283
00:47:41,990 --> 00:47:39,520
so the

1284
00:47:43,589 --> 00:47:42,000
the next question from julie bookman

1285
00:47:46,710 --> 00:47:43,599
um i'm sorry

1286
00:47:50,710 --> 00:47:48,710
let's see from julie book and write how

1287
00:47:53,750 --> 00:47:50,720
frequently does the drop song collect

1288
00:47:56,710 --> 00:47:53,760
temperature data and is drops on data

1289
00:48:00,150 --> 00:47:56,720
used to verify or qualify

1290
00:48:01,670 --> 00:48:00,160
temperature data collected by hamster

1291
00:48:02,790 --> 00:48:01,680
all right well the the data are

1292
00:48:05,349 --> 00:48:02,800
collected i'm trying to remember what

1293
00:48:07,990 --> 00:48:05,359
the number is it's like 1 or 10 hertz

1294
00:48:10,230 --> 00:48:08,000
that's about 1 to 10 times per second so

1295
00:48:11,510 --> 00:48:10,240
very high resolution

1296
00:48:15,750 --> 00:48:11,520
so we get

1297
00:48:18,150 --> 00:48:15,760
very basic extreme vertical resolution

1298
00:48:20,230 --> 00:48:18,160
which is extremely helpful

1299
00:48:22,230 --> 00:48:20,240
the hamster unfortunately is on the

1300
00:48:24,790 --> 00:48:22,240
other aircraft so we're not able to

1301
00:48:27,910 --> 00:48:24,800
verify the hamster profiles although in

1302
00:48:30,390 --> 00:48:27,920
in one of our test flights in 2011

1303
00:48:33,190 --> 00:48:30,400
uh we flew scanning his hamster and the

1304
00:48:34,950 --> 00:48:33,200
drop signs together uh for two flights

1305
00:48:37,510 --> 00:48:34,960
uh that and we were able to collect the

1306
00:48:41,349 --> 00:48:37,520
data set that was used to to verify the

1307
00:48:43,190 --> 00:48:41,359
retrieval algorithm for hamster now uh

1308
00:48:45,270 --> 00:48:43,200
within our hurricane flights you know

1309
00:48:47,910 --> 00:48:45,280
scanning his and drop center on on the

1310
00:48:49,510 --> 00:48:47,920
same uh aircraft and scanning his also

1311
00:48:52,069 --> 00:48:49,520
gets vertical profiles of temperature

1312
00:48:54,630 --> 00:48:52,079
and humidity uh primarily in the clear

1313
00:48:57,910 --> 00:48:54,640
air so it uh we are able to use the

1314
00:49:01,430 --> 00:48:57,920
drops on data to validate or verify the

1315
00:49:06,309 --> 00:49:03,750
okay thank you scott we're uh actually

1316
00:49:08,549 --> 00:49:06,319
seeing a video of a fly over uh from the

1317
00:49:10,870 --> 00:49:08,559
belly of the global hawk right now uh as

1318
00:49:14,390 --> 00:49:10,880
it flew over hurricane carl

1319
00:49:15,589 --> 00:49:14,400
in the eastern pacific ocean um

1320
00:49:18,790 --> 00:49:15,599
and i think that was from the grip

1321
00:49:19,990 --> 00:49:18,800
mission in 2010.

1322
00:49:22,069 --> 00:49:20,000
there's another question that came

1323
00:49:23,829 --> 00:49:22,079
through from christopher anderson and

1324
00:49:26,309 --> 00:49:23,839
christopher wants to know uh was the

1325
00:49:28,150 --> 00:49:26,319
global hawk custom made by lockheed or

1326
00:49:31,430 --> 00:49:28,160
was it repurposed from

1327
00:49:34,230 --> 00:49:31,440
the navy or air force version

1328
00:49:37,910 --> 00:49:34,240
i guess we can go over to maybe tom or

1329
00:49:39,910 --> 00:49:37,920
uh scott whoever wants to answer that

1330
00:49:42,230 --> 00:49:39,920
yeah um yeah i could probably speak to

1331
00:49:44,230 --> 00:49:42,240
that this this uh like i mentioned uh

1332
00:49:47,109 --> 00:49:44,240
earlier this aircraft behind me was

1333
00:49:50,230 --> 00:49:47,119
actually the technology demonstrator

1334
00:49:53,190 --> 00:49:50,240
built by northrop grumman ryan back in

1335
00:49:57,109 --> 00:49:53,200
mid 90s and it first flew in 1998 so

1336
00:49:59,349 --> 00:49:57,119
these aircraft were accessed by the air

1337
00:50:00,870 --> 00:49:59,359
we force them but they are they are

1338
00:50:03,430 --> 00:50:00,880
essentially what the air force have

1339
00:50:05,430 --> 00:50:03,440
thrown as their glock 10 aircraft they

1340
00:50:07,349 --> 00:50:05,440
have a larger version of it now that

1341
00:50:09,589 --> 00:50:07,359
they're flying opposition

1342
00:50:17,349 --> 00:50:09,599
and nasa has actually obtained a couple

1343
00:50:19,510 --> 00:50:18,630
thank you tom

1344
00:50:21,109 --> 00:50:19,520
um

1345
00:50:23,670 --> 00:50:21,119
we have one more question says how many

1346
00:50:26,549 --> 00:50:23,680
research planes would be flying during a

1347
00:50:29,910 --> 00:50:26,559
hurricane at one time will both planes

1348
00:50:32,150 --> 00:50:29,920
be flying or will it just be one

1349
00:50:33,910 --> 00:50:32,160
well we'll always be flying just one at

1350
00:50:36,390 --> 00:50:33,920
a time

1351
00:50:38,309 --> 00:50:36,400
as part of hs3 we don't have the

1352
00:50:40,630 --> 00:50:38,319
capability or manpower at the moment to

1353
00:50:42,150 --> 00:50:40,640
fly both simultaneously

1354
00:50:44,069 --> 00:50:42,160
in terms of the number of aircraft that

1355
00:50:46,470 --> 00:50:44,079
could be flying in the storm at any one

1356
00:50:48,390 --> 00:50:46,480
time it could be multiple aircraft you

1357
00:50:49,910 --> 00:50:48,400
you could potentially have one of our

1358
00:50:51,510 --> 00:50:49,920
global hawks

1359
00:50:53,910 --> 00:50:51,520
the noaa

1360
00:50:56,150 --> 00:50:53,920
p3 aircraft which is sort of a load of

1361
00:50:58,309 --> 00:50:56,160
mid-level flying aircraft

1362
00:51:00,069 --> 00:50:58,319
there's a noaa gulfstream four aircraft

1363
00:51:01,270 --> 00:51:00,079
that flies at uh somewhere higher

1364
00:51:03,270 --> 00:51:01,280
altitude

1365
00:51:04,630 --> 00:51:03,280
and then potentially air force aircraft

1366
00:51:07,430 --> 00:51:04,640
out there as well

1367
00:51:09,430 --> 00:51:07,440
back in 2010 during our

1368
00:51:11,910 --> 00:51:09,440
grip campaign or genesis and rapid

1369
00:51:13,270 --> 00:51:11,920
intensification experiment uh at one

1370
00:51:15,190 --> 00:51:13,280
point we actually had i think five

1371
00:51:18,390 --> 00:51:15,200
aircraft in the storm at one point there

1372
00:51:20,870 --> 00:51:18,400
was a three nasa aircraft uh two no

1373
00:51:22,549 --> 00:51:20,880
aircraft uh and at various times in air

1374
00:51:24,630 --> 00:51:22,559
force aircraft so

1375
00:51:28,710 --> 00:51:24,640
it is possible to have multiple aircraft

1376
00:51:33,030 --> 00:51:30,710
thank you scott um before we get back to

1377
00:51:35,030 --> 00:51:33,040
questions i just want to identify the

1378
00:51:38,069 --> 00:51:35,040
partners because this is a

1379
00:51:39,910 --> 00:51:38,079
quite an immense effort um coming

1380
00:51:42,630 --> 00:51:39,920
together there are several nasa centers

1381
00:51:45,109 --> 00:51:42,640
involved with uh with hs3 wallabies

1382
00:51:47,589 --> 00:51:45,119
flight facility is one center where the

1383
00:51:50,390 --> 00:51:47,599
the global hawks will be based um we

1384
00:51:52,390 --> 00:51:50,400
have ames research center uh the earth

1385
00:51:54,230 --> 00:51:52,400
science project office is located there

1386
00:51:56,390 --> 00:51:54,240
and they manage the project goddard

1387
00:51:58,390 --> 00:51:56,400
space flight center the dryden research

1388
00:52:00,309 --> 00:51:58,400
center where tom miller is broadcasting

1389
00:52:02,549 --> 00:52:00,319
from the marshall space flight center in

1390
00:52:05,349 --> 00:52:02,559
hultsville alabama and nasa's jet

1391
00:52:07,030 --> 00:52:05,359
propulsion laboratory in california

1392
00:52:08,950 --> 00:52:07,040
in addition to nasa though there are

1393
00:52:11,270 --> 00:52:08,960
other outside partners that have

1394
00:52:13,829 --> 00:52:11,280
contributed quite a bit to this mission

1395
00:52:15,910 --> 00:52:13,839
noaa's hurricane research division

1396
00:52:18,309 --> 00:52:15,920
is a is a part of this mission and the

1397
00:52:19,829 --> 00:52:18,319
earth system research laboratory the

1398
00:52:21,589 --> 00:52:19,839
national centers for environmental

1399
00:52:24,390 --> 00:52:21,599
prediction the naval post graduate

1400
00:52:26,790 --> 00:52:24,400
school the naval research laboratory

1401
00:52:29,190 --> 00:52:26,800
norfolk grumman

1402
00:52:31,349 --> 00:52:29,200
encar the nasa uh the national center

1403
00:52:33,190 --> 00:52:31,359
for atmospheric research state

1404
00:52:35,270 --> 00:52:33,200
university of new york at albany

1405
00:52:37,030 --> 00:52:35,280
university of maryland baltimore county

1406
00:52:39,030 --> 00:52:37,040
university of wisconsin and the

1407
00:52:41,750 --> 00:52:39,040
university of utah so as you can see

1408
00:52:43,589 --> 00:52:41,760
this is a quite an effort that

1409
00:52:45,030 --> 00:52:43,599
brings together all of these scientific

1410
00:52:47,430 --> 00:52:45,040
organizations

1411
00:52:49,990 --> 00:52:47,440
um just a reminder before we get to the

1412
00:52:52,710 --> 00:52:50,000
next question that the all of these

1413
00:52:58,230 --> 00:52:52,720
videos and images will be on the nasa

1414
00:52:59,750 --> 00:52:58,240
hs3 website nasa.gov slash hs3

1415
00:53:01,990 --> 00:52:59,760
and we also have

1416
00:53:03,990 --> 00:53:02,000
additional information on the nasa.gov

1417
00:53:06,230 --> 00:53:04,000
hurricane page

1418
00:53:07,270 --> 00:53:06,240
okay let's take another question

1419
00:53:09,430 --> 00:53:07,280
um

1420
00:53:10,470 --> 00:53:09,440
let's see from twitter

1421
00:53:14,230 --> 00:53:10,480
uh

1422
00:53:17,109 --> 00:53:14,240
bear with me for just a moment

1423
00:53:20,950 --> 00:53:17,119
what was the deadliest storm of 2012.

1424
00:53:22,710 --> 00:53:20,960
we'll throw that one over to scott

1425
00:53:25,270 --> 00:53:22,720
uh you know i don't have

1426
00:53:26,870 --> 00:53:25,280
that information offhand um

1427
00:53:29,349 --> 00:53:26,880
you know my focus last year was

1428
00:53:32,309 --> 00:53:29,359
primarily while we were in the field uh

1429
00:53:34,390 --> 00:53:32,319
superstorm sandy was probably uh

1430
00:53:35,750 --> 00:53:34,400
the deadliest but i can't confirm that

1431
00:53:39,990 --> 00:53:35,760
it's certainly

1432
00:53:44,549 --> 00:53:42,470
brian do you happen to uh do you want to

1433
00:53:47,030 --> 00:53:44,559
add into that

1434
00:53:48,309 --> 00:53:47,040
uh yeah i don't have that

1435
00:53:51,030 --> 00:53:48,319
um

1436
00:53:53,109 --> 00:53:51,040
right on hand either but i think that's

1437
00:53:55,750 --> 00:53:53,119
correct the only other storm of

1438
00:53:57,109 --> 00:53:55,760
significance that made landfall was

1439
00:53:58,710 --> 00:53:57,119
isaac

1440
00:53:59,829 --> 00:53:58,720
and that did cause some issues too but

1441
00:54:01,030 --> 00:53:59,839
no i

1442
00:54:01,829 --> 00:54:01,040
don't have that right in front of me it

1443
00:54:03,670 --> 00:54:01,839
would be

1444
00:54:05,829 --> 00:54:03,680
on the national hurricane center website

1445
00:54:08,150 --> 00:54:05,839
though you can look up the previous

1446
00:54:09,510 --> 00:54:08,160
years or any years tropical cyclone

1447
00:54:11,430 --> 00:54:09,520
reports or

1448
00:54:14,309 --> 00:54:11,440
tcr's they're called

1449
00:54:16,390 --> 00:54:14,319
so they can just look on the

1450
00:54:17,270 --> 00:54:16,400
nhc.noaa.gov

1451
00:54:19,990 --> 00:54:17,280
and

1452
00:54:21,829 --> 00:54:20,000
look for the tropical cyclone reports

1453
00:54:23,829 --> 00:54:21,839
okay thanks brian

1454
00:54:26,630 --> 00:54:23,839
um one more question from youtube uh do

1455
00:54:28,870 --> 00:54:26,640
you stage locations overseas for other

1456
00:54:32,069 --> 00:54:28,880
tropical cyclone areas besides the

1457
00:54:37,190 --> 00:54:34,950
um for hs3 we're not we're

1458
00:54:39,030 --> 00:54:37,200
simply focused on the atlantic uh there

1459
00:54:42,150 --> 00:54:39,040
is another earth venture

1460
00:54:43,750 --> 00:54:42,160
sub-orbital project called aatrex which

1461
00:54:45,670 --> 00:54:43,760
uh expects to have one of their

1462
00:54:47,589 --> 00:54:45,680
deployments out of guam i believe this

1463
00:54:49,990 --> 00:54:47,599
year and tom can probably speak more to

1464
00:54:54,549 --> 00:54:51,670
yeah that's correct scott we uh we'll

1465
00:54:59,030 --> 00:54:54,559
plan to go to uh guam earlier uh early

1466
00:55:01,910 --> 00:55:00,390
all right thank you both

1467
00:55:03,910 --> 00:55:01,920
um

1468
00:55:07,109 --> 00:55:03,920
do uh brian do you have any additional

1469
00:55:09,589 --> 00:55:07,119
questions for the the team

1470
00:55:11,270 --> 00:55:09,599
no i don't this was a lot of very good

1471
00:55:12,870 --> 00:55:11,280
questions asked asked by some other

1472
00:55:14,710 --> 00:55:12,880
folks too

1473
00:55:17,349 --> 00:55:14,720
okay um

1474
00:55:18,630 --> 00:55:17,359
marilyn tom and scott

1475
00:55:24,710 --> 00:55:18,640
are there any other things that you want

1476
00:55:29,109 --> 00:55:26,950
can't think of anything

1477
00:55:33,349 --> 00:55:29,119
okay so the the first

1478
00:55:34,710 --> 00:55:33,359
the first flight is august 20th

1479
00:55:37,030 --> 00:55:34,720
and that's leaving that's departing

1480
00:55:39,750 --> 00:55:37,040
wallops that'll be the first potential

1481
00:55:41,589 --> 00:55:39,760
science fight uh our operational window

1482
00:55:43,510 --> 00:55:41,599
for science flights is august 20th to

1483
00:55:45,829 --> 00:55:43,520
about september 23rd

1484
00:55:47,430 --> 00:55:45,839
um of course whether or not we fly that

1485
00:55:48,950 --> 00:55:47,440
particular day or any other particular

1486
00:55:51,109 --> 00:55:48,960
day depends on whether targets are

1487
00:55:52,950 --> 00:55:51,119
available uh depends on the weather at

1488
00:55:54,470 --> 00:55:52,960
wallops because we're an unmanned

1489
00:55:58,950 --> 00:55:54,480
aircraft

1490
00:56:01,030 --> 00:55:58,960
with pilots to act as the eyes

1491
00:56:05,349 --> 00:56:01,040
of the pilots on the ground

1492
00:56:07,589 --> 00:56:05,359
so bad whether it was keep us grounded

1493
00:56:09,829 --> 00:56:07,599
but the planes will actually transit uh

1494
00:56:12,710 --> 00:56:09,839
the week of the august 12th so they will

1495
00:56:13,910 --> 00:56:12,720
leave dryden and landon at wallops at

1496
00:56:18,789 --> 00:56:13,920
that time and that will that's when

1497
00:56:22,870 --> 00:56:21,030
okay and the peak of hurricane season

1498
00:56:25,109 --> 00:56:22,880
is usually the first or second week of

1499
00:56:27,270 --> 00:56:25,119
september it's around september 10th or

1500
00:56:30,309 --> 00:56:27,280
so september 10.

1501
00:56:32,390 --> 00:56:30,319
so we're hoping for a number of cyclones

1502
00:56:35,829 --> 00:56:32,400
tropical cycles out there to study

1503
00:56:37,829 --> 00:56:35,839
um nadine was very cooperative last year

1504
00:56:39,910 --> 00:56:37,839
scott how long did nadine hang around

1505
00:56:41,190 --> 00:56:39,920
last year i don't remember the exact

1506
00:56:44,150 --> 00:56:41,200
number of days i think it was on the

1507
00:56:45,589 --> 00:56:44,160
order of about 24 to 28 days something

1508
00:56:49,190 --> 00:56:45,599
like that i think it was the fifth

1509
00:56:50,950 --> 00:56:49,200
longest uh storm on record uh the odd

1510
00:56:53,349 --> 00:56:50,960
thing about last year was it was a very

1511
00:56:55,349 --> 00:56:53,359
active season uh you know obviously we

1512
00:56:57,430 --> 00:56:55,359
got all the way up at least through s on

1513
00:57:00,309 --> 00:56:57,440
the list of names and yet during the

1514
00:57:02,789 --> 00:57:00,319
five weeks we were in the field uh we

1515
00:57:04,549 --> 00:57:02,799
really only had a couple of storms occur

1516
00:57:07,030 --> 00:57:04,559
uh fortunately for us

1517
00:57:09,190 --> 00:57:07,040
nadine stuck around for a long time and

1518
00:57:10,549 --> 00:57:09,200
provided some very useful information it

1519
00:57:13,109 --> 00:57:10,559
was a storm that

1520
00:57:15,510 --> 00:57:13,119
by all uh right should have died much

1521
00:57:17,190 --> 00:57:15,520
earlier than it did and yet it somehow

1522
00:57:19,030 --> 00:57:17,200
kept going and we collected some very

1523
00:57:21,030 --> 00:57:19,040
interesting data that i think will tell

1524
00:57:22,630 --> 00:57:21,040
us a little bit about how it was able to

1525
00:57:23,990 --> 00:57:22,640
maintain itself and then eventually

1526
00:57:25,270 --> 00:57:24,000
redevelop

1527
00:57:26,950 --> 00:57:25,280
and this is another case where the

1528
00:57:28,789 --> 00:57:26,960
capability of the airplane is really

1529
00:57:31,430 --> 00:57:28,799
important because we were able to go all

1530
00:57:33,829 --> 00:57:31,440
the way over to the azores and and spend

1531
00:57:39,349 --> 00:57:33,839
time in nadine so that's that long-range

1532
00:57:43,589 --> 00:57:41,589
thank you both um and again for anyone

1533
00:57:46,549 --> 00:57:43,599
who wants more information on um how

1534
00:57:48,950 --> 00:57:46,559
nasa covered um hurricane nadine over

1535
00:57:51,430 --> 00:57:48,960
the long course

1536
00:57:54,630 --> 00:57:51,440
of life that it had go to nasa.gov

1537
00:57:55,910 --> 00:57:54,640
hurricane and click on the 2012 archive

1538
00:57:57,430 --> 00:57:55,920
and you'll see information from the

1539
00:58:00,710 --> 00:57:57,440
different nasa satellites as well as

1540
00:58:02,470 --> 00:58:00,720
some of the hs3 input in there

1541
00:58:05,190 --> 00:58:02,480
um

1542
00:58:07,270 --> 00:58:05,200
that concludes our google hangout and i

1543
00:58:09,430 --> 00:58:07,280
just want to remind everybody that

1544
00:58:11,349 --> 00:58:09,440
this video will be archived on the nasa

1545
00:58:12,710 --> 00:58:11,359
goddard youtube channel which is nasa

1546
00:58:14,390 --> 00:58:12,720
explorer

1547
00:58:17,430 --> 00:58:14,400
for more information you can go to the

1548

hs3 website which is nasa.gov

1549
00:58:22,630 --> 00:58:20,559
hs3 and again all of the videos that you

1550
00:58:25,190 --> 00:58:22,640
saw playing during the school hangout

1551
00:58:27,109 --> 00:58:25,200
and the images will also be posted up

1552
00:58:28,630 --> 00:58:27,119
there
