Estimation of Direct Radiative Effects of Background and Smoke Aerosol in the IR Spectral Region for Siberian Summer Conditions

Resumo

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