Relationships between the optical and microphysical parameters of near-ground aerosol condensation activity

Abstract

The results of measurements of the dependences of the aerosol optical characteristics on the relative humidity of air in artificial condensation processes are analyzed. The dependences of the condensation growth factors on the dry particle size are calculated and their statistical analysis is performed. The regression relation between the measured optical parameters of condensation activity and the Hanel parameter for the aerosol volume concentration is obtained. The possibility of the estimation of the Hanel parameter from the values of the refractive index of dry and humidified particles is shown.
