The Soil Moisture Active Passive (SMAP) Mission [PDF]

Proceedings of the IEEE, 2010
The Soil Moisture Active Passive (SMAP) mission is one of the first Earth observation satellites being developed by NASA in response to the National Research Council's Decadal Survey. SMAP will make global measurements of the soil moisture present at the Earth's land surface and will distinguish frozen from thawed land surfaces.
