[ MUSIC ]

2
00:00:01,770 --> 00:00:07,160
If you're on the ground during a thunderstorm, you might witness a spectacular show of lightning.

3
00:00:07,160 --> 00:00:12,840
But if you're observing that same thunderstorm from the vantage point of the International Space Station,

4
00:00:12,840 --> 00:00:16,610
you might see a bolt of energy shooting up from the clouds.

5
00:00:16,610 --> 00:00:21,100
And it might be red. Or blue. Or even green.

6
00:00:21,100 --> 00:00:25,670
These particle outbursts are like nothing seen from the ground,

7
00:00:25,670 --> 00:00:30,720
and may prove useful to predict weather outcomes more precisely, better understand

8
00:00:30,720 --> 00:00:37,370
changes to our climate and increase the safety of planes and ships approaching dangerous storms.

9
00:00:37,370 --> 00:00:48,230
They have names that sound like they were taken from a fantasy novel: 

10
00:00:48,230 --> 00:00:53,570
Blue Jet. Gigantic Jet. Red Sprite. Halos and Elves.

11
00:00:53,570 --> 00:01:00,720
But all belong to a more scientific sounding family, transient luminous events or TLEs;

12
00:01:00,720 --> 00:01:08,980
flashes and glows that appear above storms that are results of activity occurring in and below those storms.

13
00:01:08,980 --> 00:01:15,790
Dr. Timothy Lang is a lead research aerospace technologist at NASA's Marshall Space Flight Center.

14
00:01:15,790 --> 00:01:20,560
He explains how two key observational instruments aboard the orbiting laboratory

15
00:01:20,560 --> 00:01:25,910
are helping scientists better understand these colorful bursts of energy: 

16
00:01:25,910 --> 00:01:34,150
"We use the Lightning Imaging Sensor, or LIS, to map lightning in two dimensions with global-scale coverage.

17
00:01:34,150 --> 00:01:37,540
It shows us where the thunderstorms are taking place,

18
00:01:37,540 --> 00:01:45,580
and how powerful each one is based on the size of its lightning flashes. So it's akin to a macro camera.

19
00:01:45,580 --> 00:01:50,040
Another instrument, the Atmosphere-Space Interactions Monitor, or ASIM,

20
00:01:50,040 --> 00:01:56,710
is operated by the European Space Agency. ASIM gives us very fine detail of a TLE's flash.

21
00:01:56,710 --> 00:02:00,490
In essence, it's akin to a micro camera."

22
00:02:00,490 --> 00:02:06,100
Torsten Neubert, ASIM Principal Investigator at Denmark's National Space Institute

23
00:02:06,100 --> 00:02:11,900
adds that "ASIM and LIS make observations in different ranges of the color spectrum,

24
00:02:11,900 --> 00:02:15,800
allowing for different views of these particle events."

25
00:02:15,800 --> 00:02:26,140
So, LIS is macro; ASIM is micro, and together they provide a powerful combination for exploring lightning and TLEs.

26
00:02:26,140 --> 00:02:32,220
The space station offers an excellent vantage point to scientists studying TLEs.

27
00:02:32,220 --> 00:02:39,070
At about 250 miles up, it is much closer to these phenomenon than a geosynchronous satellite.

28
00:02:39,070 --> 00:02:43,450
Further, the stations' orbit allows for coverage of storms world-wide.

29
00:02:43,450 --> 00:02:50,970
All this allows LIS and ASIM to produce a unique space-based dataset of thunderstorms and their effects,

30
00:02:50,970 --> 00:02:55,320
which in turn helps support other observational instruments.

31
00:02:55,320 --> 00:02:59,790
LIS for example, has been used to calibrate instruments and verify data

32
00:02:59,790 --> 00:03:05,210
for the Geostationary Lightning Mapper on NASA and NOAA's GOES satellites,

33
00:03:05,210 --> 00:03:11,850
and will also support the lightning imager on the European satellite, Meteosat Third Generation.

34
00:03:11,850 --> 00:03:18,440
This support helps make data produced by these sensors the highest quality for serving the public.

35
00:03:18,440 --> 00:03:25,250
From the space station, LIS can provide lightning data in near-realtime for the benefit of those on Earth.

36
00:03:25,250 --> 00:03:30,850
It can report lightning nearing dry areas of forests prone to wildfires.

37
00:03:30,850 --> 00:03:34,680
It's integrated into the NOAA Aviation Weather Center's operations,

38
00:03:34,680 --> 00:03:41,740
which provides weather forecasts and warnings to the US and international aviation and maritime communities.

39
00:03:41,740 --> 00:03:44,770
And, over time, it can map data points to help scientists

40
00:03:44,770 --> 00:03:50,870
observe changes to our climate over broad tracts of land and sea.

41
00:03:50,870 --> 00:03:56,390
In short, studying lightning and its effects both below and above the clouds

42
00:03:56,390 --> 00:04:00,420
can have a big impact on how we view our planet.

43
00:04:00,420 --> 00:04:04,470
Doing so from the International Space Station is improving that view

44
00:04:04,470 --> 00:04:08,440
in ways that couldn't be accomplished anywhere else.
