Abstract : Atmospheric transmissions are computed for the 15 micron CO2 absorption band. Carbon dioxide absorption is computed using the quasi-random band model (QRBM) with the line positions and strengths as given by Young (1964, corrected 1965). The Lorentz line shape is assumed and the mean half width is determined from the absorption measurements of Burch et el. (1962). The water vapor absorption in this frequency region is computed from an empirical model of Davis and Viezee (1964). The Curtis-Godson approximation is assumed for non-homogeneous vertical atmospheric paths. Frequency interval transmissions are computed for 10/cm increments using a modified triangular response function compatible with QRBM increments of 1/cm. Atmospheric radiation intensities as received at ground level are computed from the integral form of the transfer equation. A criterion is established for determining integration error. The computed spectral intensities are compared with measured intensities. (Author)
