Control over the greenhouse gas concentration in the atmosphere using their remote detection optical means appears to be an urgent task in the contemporary world. The paper presents results of analyzing the open spectral databases in the wavenumber range of 500...10.000 cm–1 to identify the carbon dioxide. It provides computation results of the optical density and simulation matrices of the carbon dioxide spectra cross-correlation with the atmospheric air components making it possible to determine the optimal spectral ranges in detecting and measuring the carbon dioxide concentration in the atmosphere. In accordance with the obtained results, optical devices for identifying the CO2 suitable for the established ranges are selected.
