[slate] NASA satellites provide views

2
00:00:04,160 --> 00:00:08,310
of actively burning fires. The smoke plumes that are leaving those fires

3
00:00:08,330 --> 00:00:12,370
changing air quality across this country and around the world.

4
00:00:12,390 --> 00:00:16,480
And that information provides some of the first indications of new wildfires

5
00:00:16,500 --> 00:00:20,600
that then gets sent down to managers on the ground who have to make day to day decisions 

6
00:00:20,620 --> 00:00:24,800
on how to fight those wildfires. [slate]

7
00:00:24,820 --> 00:00:28,850
Some place is always burning. And from NASA's view from space

8
00:00:28,870 --> 00:00:32,910
we can detect those wildfires and start to put together the picture of how fires 

9
00:00:32,930 --> 00:00:37,020
contribute to changes in the entire Earth system. Fires

10
00:00:37,040 --> 00:00:41,170
as far away as Africa or Australia add greenhouse gasses to the atmosphere 

11
00:00:41,190 --> 00:00:45,230
changing our planet. Smoke from those fires can drift and change

12
00:00:45,250 --> 00:00:49,280
air quality across cities. And at NASA our job is to take

13
00:00:49,300 --> 00:00:53,370
our 20 satellite instruments that are detecting active fires

14
00:00:53,390 --> 00:00:57,480
observing the smoke and ash that leaves those fires and

15
00:00:57,500 --> 00:01:01,670
observing the changes that link those processes together in the air system.

16
00:01:01,690 --> 00:01:05,700
[slate] El Nino has

17
00:01:05,720 --> 00:01:09,760
been changing weather patterns, redistributing rainfall around the 

18
00:01:09,780 --> 00:01:13,850
world since last October. Changing fires in Indonesia

19
00:01:13,870 --> 00:01:18,000
and then later impacting fires where the wildfire season is just getting

20
00:01:18,020 --> 00:01:22,090
started like in the southern Amazon. One of the most amazing things about 

21
00:01:22,110 --> 00:01:26,150
NASA's observations of rainfall, of satellite ground water detection

22
00:01:26,170 --> 00:01:30,230
and actively burning fires is we can understand the way in which 

23
00:01:30,250 --> 00:01:34,340
climate changes linked to El Nino are changing fires now

24
00:01:34,360 --> 00:01:38,530
and continue to change fires over the next year. Places like the Amazon

25
00:01:38,550 --> 00:01:42,580
had less rainfall as we result of El Nino and that region is now predisposed 

26
00:01:42,600 --> 00:01:46,660
to wildfires. Wildfires that could lead to smoke and changes in

27
00:01:46,680 --> 00:01:50,680
air quality across southern Brazil including during the Rio Olympics. 

28
00:01:50,700 --> 00:01:54,740
[slate] NASA satellite instruments are really critical

29
00:01:54,760 --> 00:01:58,850
to help guide the operational firefighting that's done by the forest service

30
00:01:58,870 --> 00:02:02,960
and other agencies at the Bureau of Land Management. NASA data

31
00:02:02,980 --> 00:02:07,120
captures the daily progression of those fires and that information gets fed

32
00:02:07,140 --> 00:02:11,180
directly to the ground. The fires we're seeing now around the L.A. basin

33
00:02:11,200 --> 00:02:15,250
are changing air quality for an enormous number of people that live in

34
00:02:15,270 --> 00:02:19,360
Southern California. Those fires are burning through regions that are drier this year

35
00:02:19,380 --> 00:02:23,520
than they've been in the past because of the multi-year drought that's left most of California

36
00:02:23,540 --> 00:02:27,580
ready to burn. [slate]

37
00:02:27,600 --> 00:02:31,650
NASA is actively studying fires to understand more about the way in which fires

38
00:02:31,670 --> 00:02:35,740
release smoke, changes to air quality, greenhouse gasses

39
00:02:35,760 --> 00:02:39,900
that change our whole planet. And putting those pieces together requires we

40
00:02:39,920 --> 00:02:43,940
make measurements on the ground. Using NASA aircraft we can fly through

41
00:02:43,960 --> 00:02:47,990
smoke plumes and make detailed maps of how fires are changing these ecosystems

42
00:02:48,010 --> 00:02:52,060
and we can link that information with what we can see from space. That whole puzzle

43
00:02:52,080 --> 00:02:56,180
is what keeps me and scientists like me at NASA engaged in understanding

44
00:02:56,200 --> 00:03:00,200
our changing planet. [slate]
