NESDIS Operational Soil Moisture ProductsThe Soil Moisture Operational Products System (SMOPS) combines soil moisture retrievals from multi-satellites/sensors to provide a global soil moisture map with more spatial and temporal coverage. More recently, the SMOPS has been updated to retrieve soil moisture with near-real time SMOS data and also include the soil moisture retrievals from AMSR-2 on board GCOM. The SMOPS now provides a seamless soil moisture map over global land from four satellites, including GCOM-W1, SMOS, Metop-A, and Metop-B. 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 format at standard forecast times (00Z, 06Z, 12Z and 18Z), and daily product is available in both GRIB2 and netCDF4 formats.
