The beta version of Level-2 and Level-3 radiometer soil moisture data from NASA’s Soil Moisture Active Passive (SMAP) mission is now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC).
SMAP data show surface soil moisture in the Southeastern United States on Oct. 5, 2015 when large-scale flooding was experienced all over South Carolina.
NASA SMAP observatory managers have determined its radar can no longer return data, but the mission continues to produce high-quality science with its radiometer instrument.
NASA's new satellite mission to map the water in the soil under our feet has completed its initial calibration of instrument science data.
Maps of global soil moisture were created using data from the radiometer on NASA's Soil Moisture Active Passive (SMAP) observatory. Each image is a composite of three days of data, centered on April 15, 18 and 22, 2015.
