RADIATIVE EQUILIBRIUMnIN PLANETARY ATMOSPHERESnI. APPLICATION OF THE STRONG LINE ABSORPTION LAW TO THE ATMOSPHERE OF VENUS

摘要

The interpretation of the data obtained for Venus in the 8-12|u. atmospheric window clearly requires some knowledge of the temperature distribution in the planet's upper atmosphere. For this purpose temperatures net fluxes and specific intensities were calculated for a C02-N2 atmosphere in radiative equilibrium. The wavelength, temperature, and pressure dependence of the C02 absorption, including the excited bands, was considered. Solar radiation absorbed in the clear atmosphere influences the tem perature profile distinctly. The effects of various C02 concentrations, cloud top pressure levels, and cloud reflectivities on the equilibrium temperatures are also discussed.
