Abstract
It is revealed on the basis of round-the-clock monitoring measurements of the scattering coefficient of the dry matter of submicron aerosol at the wavelength of 0.51 μm and the mass concentration of absorbing matter at the Aerosol station of IAO SB RAS in 1997–2017, that the average level of the Black Carbon fraction (BC-fraction) of aerosol P for dense winter urban smogs is 3 times greater compared to the smoke of remote forest fires. The average value P for situations with enhanced values of the aerosol scattering coefficient ο > 150 Mm-1 (meteorological visibility range less than 26 km) in forest fire smokes is 0.027±0.01, and in winter urban smog it is 0.091±0.02. The data arrays were selected using the Pcriterion implying the lower values of BC-fraction in the smokes of remote forest fires in comparison with the background aerosol.
