Abstract
The analysis of the atmospheric model, presented in the form of one and two homogeneous layers up to a height of 5 km, was carried out. The parameters of the layers are determined for the standard atmosphere, provided that the contribution to the outgoing radiation of the atmosphere in the spectral ranges of the methane absorption line 1235.95-1236 cm-1 and 1277.5-1277.55 cm-1 is equal to the contributions to the outgoing radiation of the Earth by all inhomogeneous layers which make them up. Possible correction of the air and underlying surface temperature in determination of methane content in the Earth's atmosphere is considered.
