In this study

we present an iterative algorithm for the determination of aerosol optical thickness and the surface reflectance along coastal zone from SeaWiFS measurement.The outgoing radiances and the path radiance were inferred from 6s atmospheric radiative transfer code.Numerical experiments with SeaWiFS measurement were carried out to investigate the sensitivity of the algorithm.The iterative algorithm is applied to determine the surface reflectance in the East Ocean zone of China from SeaWiFS data.
