Aquarius/SMAP Optimum Interpolation Maps: SSS Climatology
The sea surface salinity (SSS) optimum interpolation (OI) product combines observations from NASA's Aquarius/SAC-D and Soil Moisture Active-Passive (SMAP) satellite missions into a continuous and consistent multi-satellite SSS data record. View salinity maps.
Thanks to this long, continuous data record, it is possible to compute monthly climatology data. Climatology data are computed over more than a decade. In addition, anomaly data are computed relative to the OI SSS product-based monthly climatology (view anomaly maps).
