Abstract

•The generalized k-moment method is applied to pure H2O at various temperatures.•k-distributions and transmission function models are assessed against LBL data.•The method is reliable for the modeling of the radiative properties of H2O.

In the present work, a new formulation, limited to a few number of parameters, of cumulative k-distributions over narrow bands from high resolution spectra is presented. The method is described and assessed through comparisons with reference Line-By-Line (LBL) data for pure H2O, in terms of transmission spectra and cumulative k-distributions. Results demonstrate that the proposed approach is very accurate and therefore is likely to provide reliable approximate models for the cumulative k-distribution and the narrow band transmission functions in uniform media.
