摘要

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.
