Abstract:

The Monte Carlo procedures designated as LITE-I and LITE-II were developed during a previous contract period for use in studying the transport of light through the earths atmosphere under various environmental conditions. These procedures were modified to expand their application to a broader range of physical problems. LITE-I treats monochromatic light emitted from a point source, and LITE-II treats monochromatic plane sources of light. The codes were written in both ALGOL for the Burroughs B-5500 and FORTRAN-IV for other computers. The codes are sufficiently flexible to treat multiple scattering in an atmosphere in which the air density and the aerosol size distribution vary independently and arbitrarily with altitude. Provision for treating ground and cloud reflection with an albedo method is also available in the codes. A machine procedure, designated as ACC, was developed for use in converting the scattered intensities computed by the LITE codes for a given ground albedo to scattered intensities for problems where only the magnitude of the ground albedo has changed. Utilization instructions, input data formats, sample problems and the ALGOL listings of ACC and the improved versions of the LITE programs are given to aid those who wish to utilize the codes.
