Relationship between the concentration of fine particulate matter and aerosol optical depth in the Middle Urals

The article is concerned with statistical analysis of the relationship between the ground level fine aerosol concentrations and the aerosol optical depth of the atmosphere. The aerosol characteristics measurements at two monitoring sites in the Middle Urals (Yekaterinburg city and the background region) combined with meteorological parameters and vegetation indices were used. Several linear models to estimate fine particulate matter concentrations using aerosol optical depth measurements and meteorological parameters are presented.
