Abstract:
Line-by-line calculations of IR radiative fluxes with the account of absorption by water vapor show that the fluxes and cooling rates are little sensitive to the step of frequency integration. This fact can be explained from the viewpoint of the probability theory. If the spectral absorption function of the water vapor molecule is considered as a random function, then the characteristics of its ”spectrum” allow only a small number of points to be used to reconstruct it. The further decrease of the separation between the points gives the ”excess” information in terms of the Shannon theorem.
