Atmospheric Transmittance/Radiance Computer Code FASCOD2,

Abstract

Modifications to the fast line-by-line atmospheric transmittance and radiance code FASCOD1B are detailed. CO2 far wings are modelled with a new sub-Lorentz lineshape which more properly accounts for foreign gas broadening. A two-parameter exponential-type form factor is developed and used for this purpose. The problem of radiative transfer in the daylight, non-LTE, upper atmosphere is addressed and a model for radiance and transmittance in such a medium is now incorporated in FASCOD2.(Author)
