Optical properties of the Venusian atmosphere and radiative heat exchange

Abstract

The present paper considers the optical properties of the Venusian atmosphere (including the gaseous components, cloud formations and haze) and their effect on the radiative heat exchange. These calculations are based on recent data on structural parameters and on the composition of the Venusian atmosphere, and also on laboratory quantitative measurements of the radiation absorption characteristics of CO2. The molecular absorption was calculated by taking into account the hot bands, the induced absorption and the temperature dependence of the absorption. The results of a theoretical model of the optical properties of the Venusian atmosphere and clouds agree very well with the observative data. We report some results of the calculations of the vertical radiation flux profiles and of the affux of radiative heat.
