Paper Abstract

Based on the theory of multiple scattering of radiation in a plane parallel atmosphere, solar direct and diffuse radiations in various spectral bands at different heights have been computed with the discrete ordinate algorithm using the radio observations, radiative observations, and retrieval from the TIROS/N operational vertical sounder (TOVS). The LOWTRAN program is also used for computation of radiative transfer parameters such as optical thickness. The computed radiation are then used to set up the statistical relationship with satellite observations in the VIS and IR. The results have shown that the correlation coefficient is up to 0.9 in the upper atmosphere and 0.70-0.85 in the lower atmosphere. Thus satellite observations in the VIS and IR channel may be used to estimate the solar direct and diffuse radiations in a cloudless atmosphere.
