Résumé

The Lebesgue averaging method was applied to the numerical simulation of the radiative transfer equation. It was found that the method ensures good accuracy, while the amount of computations with respect to the energy variable is reduced by more than three orders of magnitude. “Fast” simplified techniques for the Lebesgue processing of photon absorption cross sections in serial computations of atmospheric radiation were examined. Attention was given to the convenience of using the techniques, including by experienced users.
