For MODIS satellite imagery of the area with coordinates 50.1-50.4º N, 90.1-90.7º E for the period from May 1, 2022, to September 30, 2022, the results obtained by the proposed algorithm for retrieving land surface reflectivity are compared with those of the MOD09 algorithm. The comparisons show that for TERRA imagery, the algorithms' results are in good agreement. For AQUA satellite imagery, the algorithms' results also agree well for all the months considered except August. However, for August, the results differ significantly.
