Influence of spectroscopic error on solution of the problem of the methane concentration retrieval.
The influence of errors in spectroscopic information on the accuracy of the inverse problem of the concentration analysis is by the example of methane. The error of spectroscopy parameters in the range 900-7000 cm<sup>-1</sup> is considered for three isotope modifications of methane. Calculations for methane absorption bands from the visible to IR spectral range are presented, for which characteristics of typical and new laser emitters are known.
