SMAP-Derived 1-km Downscaled Surface Soil Moisture Product V001
Listed in NASA Earthdata CMR
This data product contains global daily 1 km resolution surface soil moisture derived from the SMAP L-band radiometer.
Description
Specifically, MODIS land surface temperature data is used with the SMAP Enhanced L2radiometer Half-Orbit 9 km EASE-Grid Soil Moisture product in a downscaling algorithm to estimate soil moisture. The data set is validated by in situ soil moisture measurements from dense soil moisture networks representing different global land cover types.
