Elemental composition and mass concentration of near surface aerosols in Moscow region during unusual weather conditions in the fall 2019

摘要

The results on elemental composition of the surface aerosols in Moscow region were studied from the data of the integrated autumn experiment. Elemental composition of aerosol particles in the atmosphere of Moscow city and in the suburb in the fall 2019 under unusual weather conditions are presented. The average daily mass concentration and fractional composition are compared with synoptic and meteorological factors, as well as with local aerosol sources. Meteorological conditions and local sources play great roles in forming aerosol elemental composition variability and its mass concentration.
