Satellite retrieval of inherent optical properties in the turbid waters of the Yellow Sea and the East China Sea

In situ-satellite match-ups of radiometric data are established in the turbid waters of the Yellow Sea and the East China Sea.Inherent optical properties（IOPs） are retrieved by match-up radiometric data and multi-band quasi-analytical algorithm（QAA）.By comparing in situ spectra-retrieved IOPs with the satellite ones of moderate resolution imaging spectroradiometer（MODIS） and medium resolution imaging spectrometer（MERIS）,the accuracy of satellite-derived IOPs is quantified.The median of the absolute percentage difference is found to be approximately 20%for the total absorption coefficient a;（λ） at green and blue-green bands,and 30%for particulate material backscattering coefficient b;（λ） throughout the visible bands.The spatial pattern and temporal variability of IOPs along the eastern coast of China are clarified based on satellite images and the QAA model.
