Abstract

Based on data of 3-year (2016-2018) measurements in the Middle Urals, we investigated the diurnal variability in aerosol characteristics: atmospheric aerosol optical depth (τ_0.5) and concentrations of fine aerosol (PM_2.5) in the surface layer of the atmosphere at urban and background sites in the Middle Urals. Also, as a part of this study, we estimated the relation between τ_0.5 and PM_2.5. The linear regression functions of the hourly PM_2.5 concentration and τ_0.5 were PM_2.5 = 2.83 × τ_0.5 + 20.35 (R=0.46) and PM_2.5 = 1.8 × τ_0.5 + 15.87 (R=0.31) for urban and background sites, respectively. In addition, the results also demonstrated significant differences in correlation for different time window during the day.
