00:00:06,230 --> 00:00:04,249
nasa observes the earth from land air

2
00:00:08,089 --> 00:00:06,240
and space to better understand the

3
00:00:10,820 --> 00:00:08,099
environmental changes taking place on

4
00:00:12,890 --> 00:00:10,830
our home planet over the next several

5
00:00:14,749 --> 00:00:12,900
months the NASA airborne science program

6
00:00:16,609 --> 00:00:14,759
will send its fleet of flying

7
00:00:18,340 --> 00:00:16,619
laboratories to locations around the

8
00:00:21,080 --> 00:00:18,350
world to study the air we breathe

9
00:00:23,359 --> 00:00:21,090
tropical storms and hurricanes melting

10
00:00:26,060 --> 00:00:23,369
polar ice sheets and how ecosystems

11
00:00:28,189 --> 00:00:26,070
respond to climate change NASA

12
00:00:30,169 --> 00:00:28,199
scientists will study ground-level air

13
00:00:32,330 --> 00:00:30,179
pollution in the Denver area in the

14
00:00:35,900 --> 00:00:32,340
fourth and final field campaign of the

15
00:00:38,540 --> 00:00:35,910
discover-aq mission the nasa p3 b and

16
00:00:40,580 --> 00:00:38,550
b200 airborne laboratories will measure

17
00:00:43,160 --> 00:00:40,590
pollution along Colorado's Front Range

18
00:00:45,740 --> 00:00:43,170
which routinely experiences unhealthy

19
00:00:48,200 --> 00:00:45,750
levels of ozone in the summer the goal

20
00:00:50,209 --> 00:00:48,210
of discover-aq is to better understand

21
00:00:50,750 --> 00:00:50,219
surface conditions where people live and

22
00:00:52,729 --> 00:00:50,760
breathe

23
00:00:54,709 --> 00:00:52,739
so future satellites can be used more

24
00:00:57,740 --> 00:00:54,719
effectively to measure air quality in

25
00:00:59,869 --> 00:00:57,750
the lower atmosphere the hurricane and

26
00:01:02,779 --> 00:00:59,879
severe storm Sentinel or hs3 mission

27
00:01:04,939 --> 00:01:02,789
will study hurricane intensity change in

28
00:01:06,980 --> 00:01:04,949
the North Atlantic using two specially

29
00:01:10,070 --> 00:01:06,990
equipped Global Hawk uninhabited aerial

30
00:01:12,200 --> 00:01:10,080
vehicles or UAVs the remotely piloted

31
00:01:14,660 --> 00:01:12,210
aircraft are uniquely suited for

32
00:01:16,820 --> 00:01:14,670
hurricane research they fly almost twice

33
00:01:19,249 --> 00:01:16,830
as high as commercial aircraft for as

34
00:01:21,350 --> 00:01:19,259
long as 30 hours providing continuous

35
00:01:24,350 --> 00:01:21,360
measurements above and around developing

36
00:01:25,999 --> 00:01:24,360
storms the use of the global Hawks is

37
00:01:28,640 --> 00:01:26,009
very complementary to satellites

38
00:01:30,740 --> 00:01:28,650
satellites give you a broad view of

39
00:01:32,330 --> 00:01:30,750
things over the entire Atlantic Basin

40
00:01:34,580 --> 00:01:32,340
but you only get maybe one or two

41
00:01:36,859 --> 00:01:34,590
snapshots a day with the global hawk

42
00:01:39,440 --> 00:01:36,869
you're not seen as why of an area but

43
00:01:42,620 --> 00:01:39,450
you're seeing a fixed area for a fairly

44
00:01:44,960 --> 00:01:42,630
continuous period of time 3 NASA

45
00:01:47,300 --> 00:01:44,970
airborne campaigns will study changes in

46
00:01:49,160 --> 00:01:47,310
earth's polar environments the

47
00:01:51,980 --> 00:01:49,170
multi-year operation IceBridge mission

48
00:01:54,499 --> 00:01:51,990
returns to Punta Arenas Chile where the

49
00:01:56,870 --> 00:01:54,509
dc-8 airborne laboratory will fly south

50
00:01:58,609 --> 00:01:56,880
to measure sea ice glaciers and ice

51
00:02:00,250 --> 00:01:58,619
sheets over key regions in West

52
00:02:02,830 --> 00:02:00,260
Antarctica we have

53
00:02:05,320 --> 00:02:02,840
back every year over the same glacier in

54
00:02:07,960 --> 00:02:05,330
Antarctica and measure with extreme

55
00:02:10,300 --> 00:02:07,970
precision how the surface elevation has

56
00:02:13,600 --> 00:02:10,310
changed from year to year and that tells

57
00:02:15,580 --> 00:02:13,610
us how much ice Antarctica is losing to

58
00:02:17,530 --> 00:02:15,590
other NASA airborne missions we'll study

59
00:02:20,380 --> 00:02:17,540
the impact of warming temperatures in

60
00:02:22,840 --> 00:02:20,390
the Arctic the arize campaign will use

61
00:02:24,820 --> 00:02:22,850
the NASA c-130 aircraft to measure

62
00:02:27,460 --> 00:02:24,830
Arctic cloud properties and surface

63
00:02:29,320 --> 00:02:27,470
characteristics over open water land and

64
00:02:31,480 --> 00:02:29,330
sea ice to see how the climate in the

65
00:02:33,610 --> 00:02:31,490
region is changing and the five-year

66
00:02:37,150 --> 00:02:33,620
carve experiment will measure carbon

67
00:02:40,000 --> 00:02:37,160
dioxide and methane in the atmosphere we

68
00:02:41,950 --> 00:02:40,010
are making airborne measurements of the

69
00:02:43,960 --> 00:02:41,960
principal gases that would be given off

70
00:02:46,000 --> 00:02:43,970
by the decomposition of thawing

71
00:02:49,960 --> 00:02:46,010
permafrost we think that they are

72
00:02:52,750 --> 00:02:49,970
susceptible to very rapid release and

73
00:02:55,420 --> 00:02:52,760
this could be a significant perturbation

74
00:02:58,750 --> 00:02:55,430
to not only the climate in Arctic but

75
00:03:00,970 --> 00:02:58,760
the entire world's climate system the

76
00:03:03,040 --> 00:03:00,980
NASA airborne science program is on a
