✦ Synopsis

The solution of the RTE equation in non-isothermal media by the SLW method is handled with the help of the local correction factor instead of the traditionally used socalled reference approach. Two methods of calculation of the correction factor are shown: one is based on the cumulative wavenumber (CW) distribution function developed with the HITEMP spectroscopic data; the other method uses the relationship between the reordered wavenumber and cumulative wavenumber. It is shown how this method is applied to different forms of the partition of absorption cross-section into gray gases. Further, it is shown theoretically that this method approaches the exact solution for non-isothermal media in the limit as the number of gray gases tends to infinity.
