Abstract: 
A non-equilibrium radiative transfer model has been applied to the 2.7 and isotopic 4.3 μm bands of CO2, together with that of H2O at 6.3 μm and the first excited vibrational levels of the nitrogen and oxygen molecules. The radiative transfer has been treated by a modified Curtis matrix method that allows inclusion of non-thermal sources, such as vibrational-vibrational energy exchange. The populations of the different levels have been obtained by solving a system of coupled equations, including those for the 15 μm bands. Results from the model are compared to previously reported results. A detailed study of where solar energy initially absorbed by CO2 bands finally goes is also presented. © 1986.
