The space satellite programs,such as CZCS/Nimbus-7,VHRSR/FY-1,OCTS/ADEOS and SeaWiFS/SeaStar,have demonstrated and proven that remote sensing is a powerful tool for understanding the spatial and temporal ocean color distribution.In general,there are two main technical keys in the processing ocean color satellite data.They are the atmospheric correction and the inversion of water-leaving radiance into water constituents (such as chlorophyll,suspended material and yellow substance) quantitatively.The SeaWiFS (sea-viewing wide field-of-view sensor) atmospheric correction algorithm for China's coastal waters is discussed. First,the major advantages of SeaWiFS are introduced.Second,in view of the problems of the SeaDAS algorithm applying in China's coastal waters,the local atmospheric correction algorithms are discussed and developed.Finally,the advantages of the loc al algorithms are presented by the comparison of the results from two different algorithms.
