WEBVTT FILE 1 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.
