Abstract:

We discuss the results of complex aerosol experiment, performed during 2014 in two Middle Ural regions: Yekaterinburg and Kourovka astronomical observatory (background region). The measurements of aerosol characteristics were conducted using sun photometers, photoelectric particle counters, aethalometers, and devices collecting aerosol samples on filters. We analyze the differences in the optical characteristics of aerosol between the two regions and specific features of its diurnal behavior, as well as interrelation between aerosol parameters in atmospheric column and near-ground layer. Estimates of how aerosol characteristics depend on meteorological conditions, including airmass back trajectories, are presented. We note that higher atmospheric turbidities are observed in Yekaterinburg than in background region, but the statistical significance of AOD differences (from 0.01 to 0.04) depends on the length of periods analyzed.

Keywords:

measurements, aerosol, aerosol optical depth, concentration, fine, coarse fractions, back trajectories, Middle Ural
