Data Description
NOAA Soil Moisture Products System (SMOPS) Daily Blended Products -
The Soil Moisture Operational Products System (SMOPS) combines soil moisture retrievals from multiple satellite sensors to provide a global soil moisture map with high spatial coverage. SMOPS provides a seamless soil moisture map over global land from six satellites, including GPM, SMAP, GCOM-W1, SMOS, Metop-A, and Metop-B. The global soil moisture maps are generated in daily intervals with the most recent 24 hours of soil moisture from multiple retrieval algorithms, and mapped with a cylindrical projection on 0.25 x 0.25 degree grid. For each grid point of the map, the output includes soil moisture values as a percentage (vol/vol) of the surface (top 1-5 cm) soil layer with associated quality information and metadata. The daily product is available in netCDF file format. The archvie period of record begins in March 2017. See the Details Section below for more information.

Notes
3/7/2024 - The NESDIS Operational Soil Moisture Products (SMOPS) products were migrated to NESDIS Common Cloud Framework (NCCF) on March 7, 2024, resulting in a file name change. There was no change to the contents of the files themselves.
