We present the results of simulation of aerosol radiative forcing, performed for typical summer conditions of Siberia (weakly turbid atmosphere, green vegetation cover). The factors determining the aerosol radiative effect at the top and bottom atmospheric boundaries (atmospheric aerosol optical depth, single scattering albedo, asymmetry factor of aerosol scattering phase function, and surface albedo) are analyzes. It is shown that the uncertainty of numerical estimates of the radiative forcing, caused by the inaccuracy of specifying of input atmospheric parameters in the typical range of errors, was ~ 20% and ~ 70% at the underlying surface level and the top of the atmosphere correspondingly.
