Abstract

The transfer of radiation in a stratified atmosphere is considered taking into account the effect of the underlying surface. Analytical expressions for the calculation of the transmittance, reflectivity and absorption capacity of the layered dispersed medium are obtained. It is shown that the absorptivity is strongly dependent on the stratification of the optical parameters of the atmosphere. It is established that the absorptivity of the atmosphere is the smallest with the highest concentration of contaminants in the surface layer of the atmosphere, in which case the absorptivity is weakly dependent on the distribution of absorption in the atmosphere. The presence of reflecting surfaces on the upper and lower boundaries of the atmosphere significantly enhances the absorptive capacity of the atmosphere.
