Abstract:

The FLARE Monte Carlo procedure, which computes the transport of monochromatic light emitted by either point or plane-parallel sources in a plane atmosphere, was made operational. The FLARE procedure treats problems involving light transport in atmospheres where the scattering and absorption processes vary with altitude. The FLARE procedure was used to compute the scattered and direct intensities as a function of direction and horizontal range at receiver altitudes of 0, 1, 2, 5, and 10 km. Problems were run for 550 nm wavelength point isotropic sources at 1, 2, 5, 20 and 80 km altitude in a model atmosphere with a ground level meteorological range of 10 km. Calculations were made for the 550 nm wavelength point isotropic source at 2 km altitude in model atmospheres with ground level meteorological ranges of 3, 10, 25, and 50 km. Additional calculations were also performed for 450, 550, and 650 nm wavelength point isotropic sources at 2 km altitude in the model atmosphere with a 10 km ground level meteorological range.
