Abstract:
A physical model that includes experimental data on and theoretical estimates of excitation processes that lead to emission of infrared radiation has been implemented in a computer program that computes infrared radiances for an earths limb viewing geometry. The nominal spectral region of this study lies between five and twenty-five micrometers and emphasis is placed on radiation originating at altitudes between 70 and 500 km. An earlier model for the transport of infrared radiation in molecular bands with Doppler line shape, accurate only for linear molecules, has been extended to bands of polyatomic molecules. A chemistry program which includes the effects of vertical transport by eddy mixing and molecular diffusion has been developed to make possible an estimate of diurnal variation in the abundances of infrared emitting species.
