What a U.S. satellite will tell CDNs about the ground beneath their feet

The satellite is looking at the moisture level in the soil. Not only is the amazingly useful, I'm sure that the global view will open up some promising new research areas from agriculture to climate changez.

Among those who will benefit most are experts involved in tracking agricultural productivity and flood risk, both of which are strongly correlated to the presence of water in the soil.

SMAP could also improve weather predictions, by helping to eliminate one of the most persistent uncertainties that forecasters face.
