Abstract:

The results of complex measurements of the near surface aerosol and gas (CO, NO, NO2, O3) content and meteoparameters are analyzed. It was shown that in spite of the stable blocking anticyclone, the cycling of the near surface wind directions occurred under the influence of the cyclone fronts. This resulted in periodical variations in the aerosol mass concentration with period of about 7 days. In the spectra of variations of the gaseous components this period is weakly displayed and is absent in the variations of the CO. The extreme values of the measured parameters were observed in the peaks of the smoke loading, the estimates of the mass concentration gave the values about M ~5000 mcg/m3. The Hanel parameter of the aerosol condensation activity for 2010 year smoke was found to be greater (0.2-0.4) than in 2002 year (0.1-0.15). In the intraannual variations of the daily mean M values, as in previous years, the five full oscillations with period about ten weeks were observed. The position of the third peak is abnormal. During the last 20 years at ZSS in June the deep minimum of the M values was stably observed. In 2010, this third maximum preceded the blocking anticyclone formation.
