Description/Abstract: The radiative code of the atmospheric model (DNM model) of the Institute of Numerical Mathematics (IVM), Russian Academy of Sciences is described. The code uses spectral transmission functions and the delta-Eddington approximation to take into account the absorption and scattering of radiation in the atmosphere due to atmospheric gases, aerosols, and clouds. The simplest regularization procedure in combination with the nonmonotonic factorization method is used to find a stable solution to the ill-conditioned system of delta-Eddington equations. Computation algorithms are presented, and the results obtained are compared to both the data of benchmark line-by-line calculations and the model data of ICRCCM international radiative programs. It was found that the DNM model yields a high accuracy of computing the thermal and solar radiation.
