Studying the accuracy of the algorithm for retrieving the surface albedo with high spatial resolution from a fragment of a satellite image

Abstract

An efficient algorithm for retrieving the albedo of a spatially inhomogeneous Lambertian surface from values of reflectance of solar radiation reflected from the “atmosphere–underlying surface” system is presented. The algorithm relies on the reflectance representation in the problem with an arbitrary surface albedo in terms of reflectances in problems for the same atmosphere with model underlying surfaces. Results of solving the model problems are presented. They demonstrate the possibility to use the algorithm in processing data of high spatial resolution (up to 15 m).
