Please acknowledge "NOAA CoastWatch/OceanWatch" when you use data from our site and cite the particular dataset DOI as appropriate.
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. Daily files are available back to the beginning of 2015.
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.
