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.
The influence of the optical interaction of clouds on the radiation fluxes in the atmosphere is studied. A model and a method for calculating the magnitude of the radiation interaction under multiple re-radiation between clouds are proposed. It is shown that the radiation interaction depends in a complex way on the optical and geometric dimensions of the clouds and their optical parameters. It is established that for certain optical sizes of clouds the radiation interaction between them is maximal. The position of the maximum of the radiation interaction between the clouds is determined by the scattering phase function radiation: with an increase in the degree of elongation of the scattering phase function, the maximum moves to the region of large optical thicknesses.
Consider the transfer of radiation in a stratified atmosphere. The analytical expressions for the calculation of transmittance, reflection and absorption ability of dispersed layered environment were obtained. It is established that the conservative scattering of radiation regime of the atmosphere is practically independent of altitude stratification of the aerosol. It is shown that the reflectivity of the atmosphere is only weakly dependent on the optical density of the surface layer with the absorption at any value of optical density of the upper layer and the single scattering albedo. The essential dependence of the absorptivity of the atmosphere from high-altitude parameters stratified atmosphere were established.
