New data set release: SMAP-derived 1-km downscaled surface soil moisture product, Version 1
The SMAP-derived 1-km downscaled surface soil moisture product, Version 1 data set is now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). This data product contains global daily 1-km resolution surface soil moisture obtained from the SMAP L-band radiometer and is available in GeoTIFF format. 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. The temporal coverage is from 1 April 2015 to 29 September 2022.
