Gail: The GPM Core, with its ability to detect falling snow,
it's one of the very first times that we've put sensors
in space to specifically look at falling snow. And we're
at that edge where rain was fifty years ago. So
we're still figuring out how to measure snow. Snow is much more
difficult than rain. Rain tends to be spherical-like drops
but if you've ever been out in a snowfall event and you've looked at your shirt
you see that snow comes in all different forms. And the sensors in space
are actually sensitive to those shapes. And we're still
trying to figure out all of that, and the GPM Core, with its
additional frequencies and information on the sensors, is going to be able
to provide us, for the first time, a lot more information about falling snow
than we've ever done before.
