摘要：
The problem of atmospheric correction for shortwave channels of a multispectral low-resolution scanning radiometer onboard the Meteor-M No. 2 satellite is considered. The existing atmospheric correction algorithms are analyzed. An atmospheric correction algorithm is developed based on special lookup tables (LUTs) generated by the authors. The LUTs contain information about the reflectance of the radiometer channels for different atmospheric conditions and observation geometry. The results of atmospheric correction have been validated for the first channel of the radiometer. The validation showed a high correlation with the reference reflectance taken from the Surface Albedo Validation Sites EUMETSAT portal. The algorithm has been additionally validated with the data from the first channel of the AVHRR radiometer onboard the MetOp-A satellite. The correlation between the reference values and the results of atmospheric correction are comparable for both radiometers.
