Abstract

A model and computer code, FASCODE1 (Fast Atmospheric Signature Code) has been developed for the line-by-line calculation of radiance and transmittance with particular applicability to the earth's atmosphere. An algorithm for the accelerated convolution of line shape functions (Lorentz, Voigt and Doppler) with spectral line data is used. The contribution from continuum absorption is included in the model. The method is described and applications of the present code, FASCOD1B, are presented.
