Weather effects on the aerosol characteristics in the surface layer of the atmosphere

On the basis of 14-year (1994–2007) series of the semi-annual (January to June) measurements of the atmospheric aerosol microstructure in Dolgoprudny, Moscow region, effects are analyzed of pressure, wind speed, precipitation, and surface temperature inversions on the aerosol particle concentration. It is shown that the weather parameters affect concentration of the particles within a certain range of sizes (0.1 to 1 μm). Concentration of the smaller particles practically does not depend on the weather conditions. The weather effects on large (> 1 μm) particle concentration are not detected due to too high variability of the latter. From three the most available weather parameters (pressure, wind, daily precipitation amount), the observed weather conditions are classified, and for the detected types of weather, typical concentrations are determined of the aerosol particles of different sizes, which allow approximately estimating, from the standard weather data, the aerosol pollution under different meteorological situations.
