Paper Abstract

Methods of empirical retrieval of chlorophyll – a and CDOM concentrations from hyperspectral ocean color data were described. We have considered cases of different relations between concentrations of these water constituents. Research area includes Japan Sea, East-China Sea, Okhotsk Sea, Barents Sea, Bering Sea, East-Siberian Sea and Chukchi Sea (water areas of different optical types) during the period from 2009 to 2014. Based on derived field data array, we created the method for building of regional empirical algorithms for concentrations of chlorophyll-a and CDOM retrieval taking into account differences of their contributions into water leaving radiance forming. In a similar manner, we have determined the most suitable spectral channels for the main satellite ocean color scanners. At the same time, we received concentrations of chlorophyll-a and CDOM with a help of tuning the semianalytical model for remote sensing reflectance (Rrs). Afterwards we carried out the quality assurance for the both approaches, comparing to shipboard data.
