Abstract
Daily measurements of atmospheric aerosol characteristics were carried out in Dolgoprudny (Moscow region) in June–August 2010. The particle concentrations at 11 size gradations within the range of 0.01–10 μm and the concentrations of cloud condensation nuclei active at water vapor supersaturation of 0.2–1% were determined. It is shown that the long anticyclonic conditions and the burning of forests and peat bogs resulted in the increase in total aerosol concentration in surface air by more than 1.5 times and in concentrations of particles with the diameter of 0.1–1 μm and > 1 μm by 5 and 10 times, respectively. The fire smoke mainly consisted of the particles with the size of 0.1–3 μm. The particles with the size of more than 5 μm were not observed. The recurrent visibility decrease up to hundreds of meters was caused by the increase in the concentration of particles with the diameter of more than 0.32μm in the air. During the smoke blanketing, the concentration of active condensation nuclei in aerosol increased almost by 20 times that created an opportunity for watering of aerosol particles and formation of the acid smog.
