Spectral reference data of carbon oxides


Carbon oxides belong to the important anthropogenic and natural climate relevant compounds. WG 3.42 continued the work with carbon monoxide and dioxide, in cooperation with guest researchers from UC London. Meanwhile, a very weak carbon monoxide band has been recorded in the third overtone of the CO molecule, and further spectra have been measured in pure material, as well as in interactions (collisional broadening) with nitrogen and synthetic air. Absorption bands of CO2 have been measured for different isotopologues in the wavelength ranges relevant for satellite remote sensing, in order to extract precise spectral line parameters.
