This report describes the derivation of the radiative transfer equation and its solution by the Gauss-Seidel iteration method. On the basis of microphysical and climatological considerations, four cloud models representing one stratus type and three cumulus types were investigated as to their optical properties and the thickness requirements for blackbody radiation. Findings are as follows 1 Reflection in the 10-micrometer infrared region is negligible 2 Given the same microstructure, a cloud appears more black in the windows of the 11- to 13-micrometer region than in any other windows in this infrared region 3 In satellite work, cloud emissivity or transmissivity should be calculated on the basis of upwelling radiances and 4 Cloud liquid water content may be a better parameter in defining thickness requirement for blackbody radiation.
