Regional bio-optical algorithm for remote estimation of the Sea of Azov's IOPs

Based on the field measurements of the light absorption spectra of phytoplankton pigments, the non-algal suspended matter, the colored dissolved organic matter and ocean color product, remote sensing reflectance, reconstructed from MODIS instruments from Aqua and Terra measurements, regression equations were obtained to restore the main biooptical characteristics in Sea of Azov: total concentration of chlorophyll a and pheopigments, coefficients of light absorption by phytoplankton pigments, non-living organic matter and coefficient of light backscattered by particles suspended at 438 nm. The daily 2D maps of these parameters were constructed in the surface layer from 2000 to 2018.
