Paper Abstract

From the results of monitoring measurements at the Aerosol Station of IAO SB RAS in 1997-2016, the temporal dynamics of annual average aerosol concentrations was found to vary only slightly with an insignificant negative trend. The BC concentration demonstrates a stable tendency to decrease with a trend of -2.3% a year, which for 20 years has led to a total decrease in the imaginary part of the complex refractive index of the dry basis of particles from 0.062 to 0.044. The trends of variability of the aerosol and BC content for every season copy the dynamics of annual average values. The annual behavior of the aerosol and BC concentrations is characterized by a winter maximum and a summer minimum.
