Atmospheric correction is an important part of the Quantitative Remote Sensing, and the most important key for atmospheric correction is Aerosol retrieval including Aerosol optical depth, Aerosol type and atmospheric diffuse transmission. But to retrieve the aerosol optical character over the turbid waters is difficult by using satellite image itself. So we advanced an atmospheric correction algorithm of QuickBird-2 imagery for turbid water coastal areas using synchronous measuring MODIS data. This algorithm is to retrieve the atmospheric properties of turbid water coastal areas based on MODIS water pixel. The relative error between the retrieval result and the MODIS aerosol product is less then 10%. On the other hand, by using the 6s Radiation Transfer Model and taking account of the adjacency effect for high spatial resolution imagery, Atmospheric correction has been applied to QuickBird-2 imagery for turbid water coastal areas. The atmospheric correction results and the analysis of retrieval errors have been given.
