Carbon monoxide CO is a marker of the atmosphere pollution caused by fires and combustion engines emission. The regular monitoring of the CO content in the atmosphere is needed to control the air quality. In the work, the results of CO atmospheric total content retrievals from the solar spectra recorded by Fourier spectrometers placed in Saint Petersburg (59.88N, 29.83E) and Kourovka (57.038N, 59.545E) stations, are presented. The impact of the difference in CO absorption line parameters in modern spectroscopic data bases on accuracy of the CO atmospheric content retrieval from the high resolution spectra is estimated.
