Atmospheric correction algorithm for short-wave channels of the MSU-MR device of the Meteor-M no. 2 satellite

Abstract

The problem of atmospheric correction for short-wave channels of a multispectral low-resolution scanning device installed on the Meteor-M No. 2 satellite is considered. To solve the problem the existing atmospheric correction algorithms are investigated. The developed atmospheric correction algorithm is based on the use of special Look-up Tables generated by the authors. Look-up Tables contain information about reflectance of the satellite device channels for various atmospheric conditions and observation geometry. The results of atmospheric correction for the first channel of the device were verified. Verification showed a high correlation with the reference reflectance, which is the data from the EUMETSAT portal Surface Albedo Validation Sites. An additional, verification of the present algorithm was also performed with the first channel data of the AVHRR device MetOp-A satellite. The correlation of the reference values and the results of atmospheric correction of both satellite devices are comparable.
