CoastWatch/OceanWatch produces 0.25-degree longitude/latitude Level-3 gridded sea-surface salinity (SSS) daily mean dataset by box averaging Soil Moisture Active Passive (SMAP) satellite observations over the global ocean.

CoastWatch/OceanWatch Level-3 SSS products are generated directly from the NASA Jet Propulsion Laboratory (JPL) SMAP Level-2B SSS near real time swath HDF5 files.   These products improve the application of satellite SSS products in NOAA by minimizing the data latency to within 24 hours of Level-2 data availability.
