A correlated k-distribution model of the heating rates for atmospheric mixtures of H{sub 2}O, CO{sub 2}, O{sub 3}, CH{sub 4}, and N{sub 2}O in the 0-2500 cm{sup {minus}1} wave number region at altitudes between 0 and 60 km

The main purposes of this paper are to first use the direct method of GGFP to calculate the transmission of the individual molecules H{sub 2}O, CO{sub 2}, O{sub 3}, CH{sub 4}, and N{sub 2}O, plus the transmission of a mixture of all these molecules. Second, to use the G2 model for overlapping k-distributions to calculate the transmission for the CH{sub 4}-N{sub 2}O and H{sub 2}O-CO{sub 2} systems in the spectral regions in which there are overlapping absorption features. For the wavenumber interval 0--2500 cm{sup {minus}1} and altitude range of 0--60 km, a calculation of the atmospheric heating rates, upward fluxes, and downward fluxes will be made for each of the above cases and compared to line by line calculations.
