This image shows global sea surface salinity (SSS) derived from data collected by the Soil Moisture Active Passive (SMAP) satellite. In this 8-day composite image, areas of higher salinity are shown in yellow and red; areas with lower salinity are shown in blue/light blue.

Using SMAP Data for Deriving Ocean Salinity

Researchers at NASA's Jet Propulsion Laboratory (JPL) created this SSS product from SMAP data using the Combined Active-Passive (CAP) retrieval algorithm. CAP was originally developed for retrieval of remotely-sensed salinity during the Aquarius/SAC-D mission (operational 2011-2015).
