Radio emission of Venus, taking into account trace gas constituents of the atmosphere

The inclusion of Venera 13 and 14 data on the concentrations of trace gases in theoretical calculations of the radio-emission spectra of Venus is considered. The absorption coefficient of the Venus atmosphere at wavelengths greater than 2 mm is determined with allowance for the nonresonant absorption of CO2 and N2 and the resonant absorption of COS. Also examined is the possible maximum contribution of COS to the Venus radio-emission spectrum, averaged over the visible disk of the planet. In addition, theoretical calculations of the radio-emission spectrum in the mm range with allowance for SO2 are compared with radio-astronomical data.
