Paper Abstract

The experiment on the study of dynamics of optical-microphysical properties of aerosol for 6 days with periodic moistening of particles in the range of the relative air humidity 45-95% was carried out for the mixed wood smoke in the Large Aerosol Chamber (volume of 1800 m3) of the Institute of Atmospheric Optics SB RAS. The dynamics of the disperse composition and complex refractive indices of fractions, extinction and scattering coefficients, lidar scattering and single scattering albedo is analyzed based on the data of spectral nephelometric measurements of the angular scattering coefficients, solution of the inverse problem for subfractions of ultrafine-, fine-, and coarse-disperse particles, as well as calculations by the Mie theory. It is shown that, in the course of smoke ageing, peculiarities of variations of aerosol characteristics in the field of the variable air humidity change significantly. An important factor in variations of optical-microphysical properties of the mixed “dry” and moistened smoke is the processes of migration of the ultrafine black carbon over the size spectrum present at all temporal stages.
