Seasonal behavior of the relationship of aerosol condensation activity with the relative content of volatile components in its composition

The relationship between the aerosol hygroscopic properties and the volume fraction of substances evaporating from particles in different temperature ranges during their artificial heating was analyzed by the method of active spectral nephelometry based on the measurement data obtained in 2000-2019. Throughout the year, there is a stable negative correlation between the parameter of condensation activity and the volume fraction of substances volatilizing in the range of 200-250°C. A stable positive correlation is observed in the temperature range from 25-75 to 160-200°C, the boundaries of the interval vary depending on the season.
