Animation of the sea surface salinity over the period of 31 March 2015 to 30 September 2021, produced using the Parameterized Rain Impact Model (PRIM) by the University of Central Florida (UCF) Central Florida Remote Sensing Lab (CFRSL), Orlando, FL; University of Washington (UW) Applied Physics Lab (APL), Seattle, WA., which provides the sea water salinity at surface, 1m depth and 5m depth, and probability of salinity stratification (PSS), rainfall rate and wind speed data. The dataset can be accessed from the PO.DAAC Portal at https://doi.org/10.5067/PRIMS2RSW1 (DOI: 10.5067/PRIMS2RSW1).
