PGAUSS-LT: A Program for Computing Optical Properties of Single Scattering Aerosol Clouds of Homogeneous Particles.
Abstract
The main purpose of PGAUSS-LT is to enable the user to compute luminous trasmittance over nonhomogeneous atmospheric paths containing an arbitrary size and number density of liquid and solid particles. The absorbing and scattering particles are assumed to be homogeneous, isotropic spherical particles made up of a material whose complex refractive index is known along with the real index of the surrounding medium. The modifications made to PGAUSS provide for (1) suppressing much of the detailed PGAUSS output and a slight change in the definition of the phase function, (2) calculating optical density per meter within the system of particles at specified wavelengths as a function of number density, (3) calculating luminous transmittance over various path lengths as a function of number density, (4) providing interpolation of the phase function over angular regions specified in the input, and (5) providing integration under the phase function over the angular regions.
