00:00:01,201 --> 00:00:06,006
SnowEx is a field and airborne campaign
sponsored by the Terrestrial Hydrology

2
00:00:06,006 --> 00:00:10,944
Program to test different remote sensing
instruments in different snow conditions.

3
00:00:11,344 --> 00:00:14,814
For NASA's SnowEx, we're going to Alaska
this year.

4
00:00:15,115 --> 00:00:17,584
We've done some work
in the western U.S.

5
00:00:17,584 --> 00:00:19,686
looking at mountain snowpack.

6
00:00:19,686 --> 00:00:22,288
This is an opportunity
to test different instruments

7
00:00:22,288 --> 00:00:24,391
in the boreal forest
and tundra environments.

8
00:00:25,425 --> 00:00:28,328
The sites that we've selected
are really representative

9
00:00:28,328 --> 00:00:33,333
of these larger biomes that are throughout
the northern latitudes.

10
00:00:33,967 --> 00:00:37,871
And Alaska really offers
a great testbed area to do that.

11
00:00:38,204 --> 00:00:39,172
There are, you know,

12
00:00:39,172 --> 00:00:43,243
some of the world's greatest researchers
already working up there studying snow.

13
00:00:43,610 --> 00:00:47,781
So to be able to go up there, partner
with them, use research sites

14
00:00:47,781 --> 00:00:52,652
that have long heritage of snow
research is a real opportunity for SnowEx.

15
00:00:52,952 --> 00:00:56,456
We'll have people on the ground,
about 40 people on the ground visiting

16
00:00:56,456 --> 00:01:01,261
each of these five sites every day,
collecting measurements on snowpack

17
00:01:01,261 --> 00:01:06,900
profiles,
snow depth, SWE, or snow water equivalent.

18
00:01:07,200 --> 00:01:10,737
At the same time, we'll have in
March, we'll have two aircraft flying.

19
00:01:11,071 --> 00:01:14,707
One will be flying SWESARR,
which is an active-passive

20
00:01:14,707 --> 00:01:17,010
microwave instrument
that was developed at Goddard.

21
00:01:17,544 --> 00:01:21,714
And the other plane will be flying
a lidar and a stereo imager.

22
00:01:22,782 --> 00:01:23,783
And in April, we have

23
00:01:23,783 --> 00:01:26,419
another campaign to look at snow albedo.

24
00:01:26,786 --> 00:01:29,856
This is the final year of the SnowEx
campaign.

25
00:01:29,856 --> 00:01:33,526
It’s a little bittersweet because,
you know, it's just been great

26
00:01:33,526 --> 00:01:37,530
working with the community,
collecting all this data.

27
00:01:37,664 --> 00:01:40,667
Open science
has been a huge aspect of SnowEx

28
00:01:40,667 --> 00:01:44,838
and hack weeks that we've had,
and that will continue to live on.

29
00:01:45,238 --> 00:01:47,240
But I think this is
just the starting point.

30
00:01:47,307 --> 00:01:47,474
You know,

31
00:01:47,474 --> 00:01:51,077
hopefully this will be a stepping stone
that will lead us to a satellite mission.

32
00:01:51,111 --> 00:01:55,648
Currently, there isn't a spaceborne
mission that's dedicated to global

33
00:01:55,648 --> 00:01:56,749
snowmass.

34
00:01:56,749 --> 00:02:00,086
The goal of SnowEx
has been to prepare the community for

35
00:02:00,753 --> 00:02:04,023
a spaceborne opportunity.
