A gridded sea surface salinity data set for the Pacific Ocean

The gridded Sea Surface Salinity (SSS) data set covers the region between 120°E – 70°W and 30°N – 30°S in the Pacific Ocean. It is based on available data collected from 1950 to 2009 mostly from Voluntary Observing Ships, TAO/TRITON moorings and Argo profilers, with complementary hydrocasts, STD, and CTD data collected during research cruises, and subsequently validated. This monthly SSS product is gridded using an objective mapping at the spatial resolution 1° x 1°. It is distributed with its associated error fields. It is an update of the SSS product presented in Delcroix et al (2011).
