Description: A method has been devised for integrating the pressure-scaled water-vapor and CO2 absorber masses from the surface to the sigma - levels used for prediction in the Naval Postgraduate School primitive equation model. Using empirical expressions for atmospheric absorptivity, scattering-reflectivity, cloud-reflectivity and earth-surface reflectivity, the useful solar insolations absorbed at earth and in the key atmospheric layers above the earth have been formulated. The terrestrial cooling effect at earth and in these same key atmospheric layers have also been formulated using recently published emissivities for the joint effects of water vapor and CO2. As a result, the radiative heating (cooling) at key levels may be ascertained for input into the atmospheric thermodynamic equation. In addition, application of atmospheric boundary-layer modelling permits determination of the surface-layer turbulent transports (in the vertical) of sensible and latent heat at the earth's surface.
