Abstract
The results of the analysis of the radiation regime of Tomsk during the period of smoky haze from forest fires in Siberian region in July 2012 are presented. It is shown that in the presence of a smoky haze the total solar radiation is weakened by 45% on the average, and ultraviolet radiation, by 60–65% in comparison with similar periods with the typical background aerosol level. Parameters of smoky haze aerosol influencing the solar radiation absorption are determined. At strong smoke, the weakening of total radiation reached 70% and almost full weakening of UV radiation was observed.
