Experimental studies of the aerosol spectrum at high-mountain conditions

Abstract The paper considers variations in the number concentration of submicron aerosols, and size distribution of aerosol particles on the Shadzhatmaz plateau.

Summary:Abstract The paper considers variations in the number concentration of submicron aerosols, and size distribution of aerosol particles on the Shadzhatmaz plateau. The aerosol dimensional spectra were plotted according to the data obtained during hours with no cloudy factors in the atmosphere, and for the measurement periods when the clouds descended so low that the cloud masses were carried by the wind directly through the measurement site. A characteristic feature of the spectrum obtained in the presence of low foggy clouds is the decrease in the fraction of the smallest aerosols (0.1-0.2 μm), compared with the measurement in clear atmosphere conditions; at the same time, the concentration of larger aerosols (0.2 μm and more) under conditions when the observer noted the movement of cloud masses through the measurement site, turned out to be higher than that for clear atmosphere conditions.
