Clouds! The Science, the Wonder & Why NASA Needs You.

14:35Andy SayerGUEST
So if I take one step back, the instrument we're using to identify clouds from Pace's point of view is called OCI, Ocean Color Instrument.
A
14:52Andy SayerGUEST
And the reason we're doing this cloud identification in the first place is because if you want to then work out cloud properties, like water content, whether it's liquid or ice, first you need to know where the clouds are.

15:06Andy SayerGUEST
And if you want to look at the surface, whether that's vegetation on land or plankton in the ocean, you need to know where the clouds are not.
A
15:15Andy SayerGUEST
So this kind of cloud identification, we often call it flagging, is the first step in a lot of satellite data processing.

15:23Andy SayerGUEST
And most of the time, unless there's snow on the ground, like Jessica mentioned, it's pretty easy because clouds are mostly fluffy, pretty bright, and they're kind of white.

Is there benefit to having the citizen scientists like spread out or does it matter? Do you want them in different parts of the country? And if so, are there holes right now in your data where like you could really use people in this state or this state?
