The Soil Moisture Operational Products System (SMOPS) combines soil moisture retrievals from multi-satellites/sensors to provide a global soil moisture map. The SMOPS provides a seamless soil moisture map over global land using data from five satellites: GPM, SMAP, GCOM-W1, MetOp-B, and Metop-C.
The global soil moisture maps are generated in 6-hourly and daily intervals with the latest 6 and 24 hours worth of soil moisture retrievals from multi-satellites/algorithms, and mapped with a cylindrical projection on 0.25 x 0.25 degree grids. For each grid point of the map, the output includes soil moisture values (%vol/vol) of the surface (top 1-5 cm) soil layer with associated quality information and metadata. The 6-hourly product is available in GRIB2 and netCDF format at standard forecast times (00Z, 06Z, 12Z and 18Z), and the daily product is also available in both GRIB2 and netCDF4 formats.
