Abstract : An atmospheric IR transmittance prediction model which includes the effects of high resolution molecular absorption, certain molecular continuum absorption, Rayleigh scattering and single and multiple scattering by spherical, polydisperse aerosol materials is summarized. The multiple-scattering codes are discussed in some detail, as are its current limitations. Representative results obtained for three aerosol models are presented, together with descriptions of conclusions which may be drawn from them. In addition, the effects on transmittance of using generalized Voight line shape profile are discussed. Complete Fortran IV source code listings, as well as UNIVAC 1108 running instructions are appended.
