Abstract
The analysis of basic spectroscopic factors, influencing atmospheric radiative transfer simulation in the methane absorption IR bands, which are used in the tasks of methane total content retrieval from the atmospheric solar spectra measurements, is carried out. The role of methane and water vapour absorption line parameters uncertainties and difference of extraterrestrial solar spectrum models is considered. A comparison with measured atmospheric spectra is made.
