(Dr. Arthur Cho) GPM is an International Satellite Mission, that would set a new standard for precipitation

6
00:04:52.880 --> 00:04:54.620
measurement from space.

7
00:04:54.620 --> 00:04:58.860
Providing a new generation of observation of rain and snow.

8
00:04:58.860 --> 00:05:01.320
In all parts of the world, every 3 hours.

00:05:07.620 --> 00:05:12.760
GPM data will advance our understanding of global water and energy cycle.

11
00:05:12.780 --> 00:05:20.640
They will also be used in a host of societal applications that range from flood forecasting, landslide warning,

12
00:05:20.640 --> 00:05:27.320
fresh water monitoring, crop prediction and all the way to the tracking water born diseases.

00:05:31.900 --> 00:05:36.560
(Dr. Gail Skofronick-Jackson) The GPM core has an active radar and a passive radiometer.

15
00:05:36.560 --> 00:05:43.620
And these two instruments are just what a doctor might use in terms of an x-ray for the radiometer

16
00:05:43.620 --> 00:05:46.200
and a CAT scan for the radar.

17
00:05:46.200 --> 00:05:50.840
To diagnose what is happening in clouds and to understand what is happening with the precipitation.
