Database was developed using in-situ water components absorption data to analyze the correlationship between absorption coefficients of suspended substances and their concentrations in the water color bands of MODIS and MERIS reflectance,respectively.Based on the bio-optical theory models and the remote sensing retrieval semi-analysis algorithm of Carder-MODIS phytoplankton optical characteristics,the sensitive bands adapting to local water optical characteristics were selected to develop empirical models of inherent optical characteristics,apparent optical parameters and component concentrations.And the remote sensing retrieval of water inherent optical characteristics and concentrations in the Hangzhou Bay at the MODIS band was achieved by this model.
