Abstract
The model of the atmosphere in the form of thin homogeneous layers is considered, which is converted into two homogeneous layers without changing the power of the outgoing radiation in the studied spectral region of the methane absorption bands 1220-1260 cm-1. The observed distortion of the spectrum of outgoing radiation of the Earth with consideration of atmospheric model in an equivalent homogeneous layer does not affect the correlation analysis. The system of equations relating changes of methane content in each of the homogeneous layers with the change of power of the outgoing radiation is given.
