Abstract

The data obtained in 2000–2019 by the method of active spectral nephelometry using artificial humidification and heating of an aerosol collected from the atmosphere are analyzed. Measuring the response of the aerosol scattering coefficient to changes in relative humidity in the range of 30 - 90% and temperatures from 25 to 250°C makes it possible to indirectly evaluate the content of soluble/volatile species in the composition of particles. A combined analysis of the hygro- and thermo-optical parameters allows us to reveal the effect of compounds evaporating at various temperatures on the hygroscopic properties of particles.
