The ratio of submicrometer and coarse particles in the aerosol size distribution under smoke and background conditions

Variability of the multi-year average ratio of number concentrations of submicrometer and coarse particles and their volume size distributions under smoke and background conditions are studied on the basis of monthly average data obtained at the Aerosol station of IAO SB RAS in 2000-2017. The data arrays on the disperse composition of particles are formed by means of the technique developed earlier, which provides for selection of the atmospheric aerosol realization using the P-criterion providing isolation of smoke and background situations on the correlation diagram of the soot fraction of submicrometer particles and the aerosol scattering coefficient.
