Delivery of new Suomi National Polar-orbiting Partnership (Suomi NPP) satellite observations will cease on November 2, 2026. Data users should transition now to alternative products from NOAA-21 and NOAA-20.Suomi NPP data announcement
Description
This data product contains global daily 1 km resolution surface soil moisture derived from the SMAP L-band radiometer. 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.
Citation is critically important for dataset documentation and discovery. This dataset is openly shared, without restriction, in accordance with the EOSDIS Data Use and Citation Guidance.
