Abstract

The parameters of condensation activity of submicron and coarse aerosol fractions and the volume scattering coefficient are compared on the basis of the data on the growth of submicron aerosol particles during artificial humidification obtained using an optical counter and an integral nephelometer. To calculate the growth factor and the Hanel parameter of condensation activity for the radii of submicron particles, an original methodological approach was applied, which used data on the dynamics of the variability of the total concentration under artificial humidification. The parameters of condensation activity obtained in spring, autumn and winter of 2020-2021 by the counter and the nephelometer are compared. Monitoring of the number concentrations was carried out in 2020-2021 within the framework of the state assignment of IAO SB RAS. The relationship of condensation activity parameters was analyzed with the financial support of the Russian Science Foundation (agreement No. 19-77-20092).
