Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The Soil Moisture Active and Passive mission (SMAP) is in the first tier of missions recommended for NASA by the Earth Science Decadal Survey. It has been selected for launch in 2015. SMAP will provide measurements of the land surface soil moisture and freeze-thaw state with near-global revisit coverage in 2-3 days. SMAP surface measurements will be coupled with hydrologic models to infer soil moisture conditions in the root zone. SMAP observations will be acquired for a period of at least three years after launch. A comprehensive validation, science, and applications program will be implemented, and all data will be made available publicly through the NASA archive centers.
