A spectral system for measuring atmospheric gaseous components based on a Brucker IFS 125M Fourier Transform Spectrometer (FTS) with a fiber-optic tracker is described. Experimental results on the determination of CO2 and H2O contents in the atmosphere above Tomsk from the analysis of atmospheric transmission spectra of solar radiation, recorded with the FTS, are presented. The atmospheric transmission spectra are compared for solar zenith angles of 34° and 78°, which show a significant quantity of oxygen collision complexes in the surface air layer.
