Based on the level 1 data and the relevant ancillary data of the Moderate-resolution Imaging Spectro-radiometer (TERRA/MODIS),the aerosol optical depth over East China Sea was retrieved by International MODIS/AIRS Processing Package (IMAPP) and Two-Channel Aerosol Retrieval Algorithm,the inverse methods were validated with Aerosol Robtic Network (AERONET) solar direct radiance measurements.The distribution characteristics of aerosol optical depth and ngstrm exponent (which symbolizes the width of particle spectrum) over East China Sea during Oct - Nov 2002 were studied.The results indicate that the aerosol optical depth obtained by both methods over East Sea and the open sea area south of Japan are basically in consistent with the result from AERONET.However,due to the influence of Case 2 water,the aerosol optical depth is a bit high along the coastal area of Bohai Sea and Yellow Sea.The characteristics of East China Sea are analyzed,which provide the basic data for retrieval method over East China Sea.
