Abstract
The results of experimental study of the condensation activity of particles of different size carried out in October 2020 till June 2021 with use of an AZ-10 optical counter, equipped with a system for artificial humidification of atmospheric aerosol collected, are considered. Hygrograms of the total aerosol scattering coefficient were simultaneously measured with a M903 integral nephelometer. The atmospheric conditions and aerosol characteristics during the measurement period were typical, which was confirmed from the comparison with long-term series of the condensation activity parameter for the scattering coefficient at an angle of 45°.
