Аннотация: The efficiency of determining the concentration of СО2 and H2O vapors in the atmosphere has been investigated taking into account the overlap of their spectral lines. It is proposed to use regression relationships established between the determined and measured parameters of the investigated medium. These ratios can be set both for fixed values of temperature and pressure, and for a set range of their values. When calculating the absorption value, all overlaps of spectral lines are taken into account, taking into account their broadening at different temperatures and pressures. This allows the method to be used in multicomponent media with strongly overlapping spectral lines. The established regression relations are resistant to errors in the measurement information, which also improves the accuracy of determining the concentrations of the component composition of the gas medium. In addition, they are determined promptly (in real time), since the calculation of concentrations using established relationships (analytical expressions) between the determined and measured values does not present computational difficulties.
