Abstract
An assessment of atmospheric aerosol composition in middle and high latitudes of Eurasia has been made by integrating long-term (longer than five years) instrumental observations of microphysical and optical characteristics of atmospheric aerosols at the Zotino Tall Tower Observatory (ZOTTO) in the middle-taiga subzone of Yenisei Siberia and Lagrangian trajectory modeling. A correlative analysis of the findings and data for anthropogenic and forest fire emissions revealed signals existing in its formation, and their origin was assessed.
