Abstract:

Using data of IR transmittance spectra of aerosol samples and data of measurements of surface aerosol optical characteristics at Zvenigorod Scientific Station, a statistical relation of the Hänel parameter of condensation activity to air relative humidity and essential chemical components of aerosol, such as sulphates, nitrates, and minerals in particles with diameters of 1–2 μm, is studied. The Hänel parameter of surface aerosol containing nitrates has been shown to decrease with the increase of the relative humidity of air. The increase in portion of nitrates in micron particles results, probably, in a few increase in the Hänel parameter. The presence of poorly soluble mineral particles in 2-μm fraction of aerosol results in the decrease in Hänel parameter. Values of the Hänel parameter characteristic for sulphate aerosol are, probably, concluded within 0.4–0.6. Seasonal changes in the Hänel parameter are caused in part by changes in chemical composition of aerosol.

Keywords:
