【 摘 要 】

The impact of aerosol is a key issue on atmospheric correction in remote sensing. The aim of this work is to evaluate the radiative impact of the aerosol type on the results of the atmospheric correction in Lake Taihu, a typical case-2 water. The atmospheric correction of MERIS images were carried out using the 6S atmospheric radiation transfer model. The water reflectances obtained by different aerosol types were compared with the measured spectral data. The correction results of the Continental and Maritime model are similar, and more reliable than the results of urban model. Continental aerosol model achieved good results in bands from 3 to 9, but in other bands, the results of maritime aerosol model are better than the continental results. Therefore, Selection of an accurate aerosol model is the primary task of atmospheric correction.
