| Zusammenfassung |
| The paper presents an investigation of aerosol seasonal variations in several
urban–industrial regions in Ukraine. Our analysis of seasonal variations of
optical and physical aerosol parameters is based on the sun-photometer
2008–2013 data from two urban ground-based AERONET (AErosol RObotic NETwork) sites in Ukraine (Kyiv,
Lugansk) as well as on satellite POLDER instrument data for urban–industrial
areas in Ukraine. We also analyzed the data from one AERONET site in Belarus
(Minsk) in order to compare with the Ukrainian sites. Aerosol amount and
optical depth (AOD) values in the atmosphere columns over the large urbanized
areas like Kyiv and Minsk have maximum values in the spring (April–May) and late
summer (August), whereas minimum values are observed in late autumn. The
results show that fine-mode particles are most frequently detected during the
spring and late summer seasons. The analysis of the seasonal AOD variations
over the urban–industrial areas in the eastern and central parts of Ukraine
according to both ground-based and POLDER data exhibits the similar traits.
The seasonal variation similarity in the regions denotes the resemblance in
basic aerosol sources that are closely related to properties of aerosol
particles. The behavior of basic aerosol parameters in the western part of
Ukraine is different from eastern and central regions and shows an earlier
appearance of the spring and summer AOD maxima. Spectral single-scattering
albedo, complex refractive index and size distribution of aerosol particles
in the atmosphere column over Kyiv have different behavior for warm
(April–October) and cold seasons. The seasonal features of fine and coarse
aerosol particle behavior over the Kyiv site were analyzed. A prevailing
influence of the fine-mode particles on the optical properties of the aerosol
layer over the region has been established. The back-trajectory and cluster
analysis techniques were applied to study the seasonal back trajectories and
prevailing directions of the arrived air mass for the Kyiv and Minsk sites. |
