摘　　要：SeaDAS软件提供的标准大气校正算法中,假设第7和第8通道的离水辐射为0,但测量数据表明,在二类水体的大气校正算法中这种假设不成立.针对中国海区的特点,选取不同的近岸二类水体大气校正方法进行分析和比较,给出了适用于近岸二类水体尤其是近岸高泥沙含量的混浊水体的大气校正方法.The normal atmospheric correction algorithms developed by SeaDAS software supposed that the radiance of the Sea-viewing Wide Field-of-View Sensor （SeaWiFS） 765 nm and 865 nm bands is zero. But practical data proved that this assumption is not tenable in the atmospheric correction algorithms for case 2 water. Several atmospheric correction algorithms were provided based on the turbid coastal and inland waters of seas in China. The better one from them was chosen after analysis and comparison, which is more suitable to processing SeaWiFS data under the specific atmospheric and oceanic situations in China.
