SMAP and Sensing Sea Surface Salinity (SSS)

Monday, July 10, 2017

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).
