As a member of the salinity gradient assessment working group, ESR provides up-to-date ocean surface salinity gradient calculations derived from satellite and Argo data as well results for salinity gradient validation.​ The results are available to view and download.


Global Aquarius meridional salinity gradient (psu/km).

Our goal is to provide a systematic estimation and assessment of satellite sea surface salinity gradients over the global ocean, including spatiotemporal variability, as well as regional analysis.
