We presented estimates of direct radiation effects (DRE) of background and smoke aerosol in the IR spectral region obtained using an original algorithm of the Monte Carlo method and OPAC models for typical summer conditions and conditions of 2012 smoke haze on the territory of Siberia. It is shown that the DRE value at the atmospheric boundaries in the thermal range with respect to the daily average radiative effect in the solar spectral region is approximately 3% under the background conditions and 10-15% under the conditions of strong turbidity.
