A description of a radiation model used for calculations of radiation transfer in a cloudless and cloudy atmosphere of the Earth is given. To parameterize functions of atmospheric transmission due to molecular absorption, exponential series are applied, with parameters determined on the basis of line-by-line calculations using modern spectroscopic databases. For effective parametrization, a simple and accurate method of taking into account the spectral dependence of the response function of recording devices has been developed. Examples are given for sensors installed on Sentinel-2A and Landsat 8 satellites.
