Soil Moisture Active Passive - Wikipedia
WebApr 18, 2016 · The SMAP spacecraft carries two instruments: a synthetic aperture radar, which is the active sensor, and a radiometer, which is the passive sensor. The mission design was to combine the high accuracy of the radiometer and the high spatial resolution of the radar to produce high quality measurements at an intermediate spatial resolution. SMAP is a directed mission of the National Aeronautics and Space Administration. The SMAP project is managed for NASA by the Jet Propulsion Laboratory, with participation by the Goddard Space Flight Center. SMAP builds on the heritage and risk reduction activities of NASA's cancelled ESSP Hydros Mission. See more Soil Moisture Active Passive (SMAP) is a NASA environmental monitoring satellite that measures soil moisture across the planet. It is designed to collect a global 'snapshot' of soil moisture every 2 to 3 days. With this … See more SMAP provides measurements of the land surface soil moisture and freeze-thaw state with near-global revisit coverage in 2–3 days.
