摘要：

NASA has initiated the Soil Moisture Active Passive (SMAP) satellite mission, as recommended by the National Research Council in their 2007 report. Set to launch in October 2014, SMAP will use a combination of active radar and a passive radiometer to provide global measurements of surface soil moisture and soil freeze/thaw state. The synergy of active and passive microwave observations, combined with SMAP's wide swath, enables measurements of soil moisture and freeze/thaw state with high resolution and adequate sensitivity, area coverage, and revisit frequency. The SMAP Applications program is designed to first increase and then sustains the interaction between application users and scientists involved in mission development. In addition to the instrument measurements and derived products for the surface layer, SMAP will also provide Level 4 data assimilation products by ingesting active and passive observations into land surface models to provide root-zone soil moisture.
