Abstract

The aim of this work is to analyze the average monthly salinity of the surface layer of the Sea of Azov according to in situ measurements in the period 1913–2018 and remote sensing measurements in the period 2015–2022. We used in situ data at 0–2 m depths, as well as SMAP V5 level 3 monthly average sea surface salinity data with better spatial resolution than similar remote sensing instruments Aquarius and SMOS (MIRAS). Using the example of the Sea of Azov, it is shown that for shallow and slightly saline water areas, the error in determining salinity from satellite measurements is 0.5–3 relative to in situ observations.
