Gail: The GPM Core, with its ability to detect falling snow,

3
00:00:08.100 --> 00:00:12.120
it's one of the very first times that we've put sensors

4
00:00:12.140 --> 00:00:16.150
in space to specifically look at falling snow. And we're

5
00:00:16.170 --> 00:00:20.180
at that edge where rain was fifty years ago. So

6
00:00:20.200 --> 00:00:24.200
we're still figuring out how to measure snow. Snow is much more

7
00:00:24.220 --> 00:00:28.220
difficult than rain. Rain tends to be spherical-like drops

8
00:00:28.240 --> 00:00:32.230
but if you've ever been out in a snowfall event and you've looked at your shirt

9
00:00:32.250 --> 00:00:36.280
you see that snow comes in all different forms. And the sensors in space

10
00:00:36.300 --> 00:00:40.330
are actually sensitive to those shapes. And we're still

11
00:00:40.350 --> 00:00:44.370
trying to figure out all of that, and the GPM Core, with its

12
00:00:44.390 --> 00:00:48.410
additional frequencies and information on the sensors, is going to be able

13
00:00:48.430 --> 00:00:52.440
to provide us, for the first time, a lot more information about falling snow

14
00:00:52.460 --> 00:00:56.470
than we've ever done before.
