Monthly and 8-day mean Level-3 satellite Sea Surface Salinity created by National Centers for Environmental Information (NCEI) from the NASA Soil Moisture Active Passive (SMAP) mission in support of the NCEI satellite level-2 data quality monitoring from 2015-04-04 to 2018-02-18 (NCEI Accession 0208018)

Aiming for near-real-time data-quality monitoring of the Level-2 satellite sea surface salinity (SSS) products, the satellite oceanography team of NOAA National Centers for Environmental Information (NCEI) has generated quick-look 1.0-degree Level-3 experimental products from the NASA Soil Moisture Active Passive (SMAP) mission Level-2b V3.0 combined active/passive (CAP) product generated by NASA Jet Propulsion Laboratory (JPL). The datasets are comprised of two respective Level-3 monthly and 8-day mean datasets. The Level-2 swath data are interpolated onto a 1.0-degree grid using equal-weighted box (“bin”) averaging.
