Abstract
Different microphysical, optical and radiative properties of aerosol were analyzed according to the 10 years of measurements (2001–2010) at the Meteorological Observatory of Moscow State University within the framework of international AERONET program. Volume aerosol size distribution was shown to have a bimodal character with dominating the fine mode aerosol particles at effective radius of reff-fine=0.15 µm. In smoke conditions reff-fine was shown to increase to 0.25 µm at extremely large aerosol optical thickness (AOT). Real and imaginary parts of refractive index are characterized by REFR=1.45, REFI=0.01 respectively, changing to REFR=1.49, REFI=0.006 for smoke aerosol. AOT seasonal changes are characterized by the increase towards warm period with a local minimum in June. The joint analysis of aerosol characteristics with the NOAA_NCEP_CPC_CAMS_OPI climatology shows the nature of these changes. For typical conditions aerosol single scattering albedo (SSA) is about 0.9 at 675 nm and is characterized by a distinct decrease with wavelength while in forest fires conditions it is significantly higher (SSA=0.95). The interaction between volume aerosol concentration of different aerosol fractions was obtained with a distinct decrease of variation towards large aerosol content.
