Monthly and 7-day mean Level-3 satellite Sea Surface Salinity created by National Centers for Environmental Information (NCEI) from the Aquarius/Satélite de Aplicaciones Científicas (SAC)-D mission in support of NCEI satellite level-2 data quality monitoring from 2011-08-26 to 2015-06-04 (NCEI Accession 0151631)

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 Aquarius/Satélite de Aplicaciones Científicas (SAC)-D satellites level-2 swath data. The datasets are comprised of two respective Level-3 monthly and 7-day mean datasets, one from the standard level-2 SSS data created by the NASA Goddard Space Flight Center's Aquarius Data Processing System (ADPS) and another from the one created by the Jet Propulsion Laboratory (JPL) based on the Combined Active-Passive (CAP) algorithm. The Level-2 swath data is interpolated onto a 1.0-degree grid using equal-weighted box (“bin”) averaging.
