Abstract : The AGGIE Monte Carlo code was modified by providing an output file giving information on the location and direction of motion for each source photon and collided photon during a run. The CUBCLD1 code was developed to analyze the collision file to determine the polar and azimuthal angle distribution of the photons escaping from each side of a box-shaped cloud. The AGGIE code was modified to evaluate hemispheric emission from a box-shaped cloud. The modified code was used to provide calculational data for both a sunlight source and ground and cloud emission. The results were compared to data reported by McKee and Cox; Harshvardhan, Weinmann, and Davies; and Zardecki. The comparison shows that AGGIE is capable of providing accurate radiation transport data used for validating the BLIRB code. jg
