“…In Belorussian cities mean AOD values are of 0.22 ± 0.04 (Minsk) and 0.21 ± 0.03 (Gomel). Ukrainian and Belorussian cities have similar sources of atmospheric pollution (Miatselskaya et al, ), associated with emissions from railway and motor‐vehicle transport (these cities are the largest transport centres), emissions from Thermal Power Plants and enterprises of engineering, chemical (Odessa, Gomel), oil‐refining (Odessa) and non‐ferrous industry (Kyiv, Dnipro). For the capitals of Slovakia, Hungary, Romania, Bulgaria and Moldova annual mean values were 0.23 ± 0.02 (Bratislava), 0.2 ± 0.02 (Budapest), 0.19 ± 0.02 (Bucharest), 0.17 ± 0.02 (Sofia) and 0.14 ± 0.03 (Chisinau), respectively.…”

This study investigates the spatial–temporal evolution of aerosols, their optical properties (aerosol optical depth [AOD] and ångström exponent [AE]) and the trend over a period of 19 years in the Eastern European countries. The data used for the study are from moderate‐resolution imaging spectroradiometer (MODIS) Terra Collection 6.1 aerosol products with the use of Dark Target algorithm for the period from 2000 to 2018. The satellite‐based AOD products were validated against the AERONET AOD measurements in four stations, located in different regions. The results demonstrate high coherence in the setting of high values of correlation (R = 0.8–0.9) and low values of root‐mean‐square error (RMSE [0.066–0.130]) and mean absolute error (MAE [0.048–0.067]). However, of the total amount of data from AERONET stations, only 68.9% of available data fall within expected error (EE) over land. Generally, all countries recorded a low AOD (83.2% less than 0.2) and high AE (82.5% higher than 1). Mean AOD and AE values varied from 0.17 ± 0.12 and 1.31 ± 0.27 (Russia) to 0.24 ± 0.14 and 1.31 ± 0.33 (Czech Republic). There was a gradual decrease in aerosol load in all countries, the highest tendencies of AOD reduction are observed in Czech Republic, Bulgaria, Slovakia and Hungary (by −0.0028, −0.0027, −0.0026 and −0.0025 per year), while the lowest tendencies of reduction are observed in Russia and Moldova (by −0.001 and −0.0006 per year). Seasonal averaged AOD values have maximum values in summer and minimum values in winter. We studied predominant aerosol types, which are based on AOD and AE interrelation, the results showed the predominance of clean continental and mixed aerosols over all countries of the region.

“…Sun photometer measurements are restricted to day-time and cloud-free conditions. Model simulations can be applied to obtain information on aerosol concentration and composition with complete spatial and temporal coverage [11,12]. The model must provide consistent information for satellite measurements validation.…”

Космічна й атмосферна фізика INTRODUCTION Aerosols are an important component in the Earth's atmosphere. Aerosols cause atmospheric pollution which influence negatively on human health. They affect the radiation balance of the atmosphere, resulting in climate change. Aerosol distribution in the Earth's atmosphere is studied using measurements from many satellite and ground-based instruments. However, the distribu

“…The coarse-mode aerosol particles concentration distributed less uniformly and located close to source areas due to the relatively short lifetime. The coarse-mode aerosol is mainly concentrated over southern and eastern regions of Ukraine, and over the Black Sea and nearby terrains (Miatselskaya et al, 2016). It is known, that steppe regions in the south-east of Ukraine often become a sources of mineral dust, up to 3 10 −4 kg m −2 , which transported by strong winds on the far distance (Birmili et al, 2008), particularly to Belarus (Miatselskaya et al, 2016).…”

“…Nitrates, sulfates, organic aerosol, and ammonia also constitute significant fractions in the region, but sea salt and inorganic carbon are minor components, 1.6, 0.8% and 1.0, 0.6% respectively. The spatial distribution of aerosol volume concentration (in µm 3 µm −2 ) for fine-mode and coarsemode aerosols in the atmosphere over Belarus and Ukraine simulated by the GEOS-Chem model and averaged over the period 2010-2013 was studied in Miatselskaya et al (2016). The fine-mode particles are distributed over the region more or less uniformly, due to their relatively long lifetime in the atmosphere.…”

“…The spatial-temporal distribution of specific aerosol types in the atmosphere over Ukraine and Belarus has been simulated by using the GEOS-Chem model (Miatselskaya et al, 2016). GEOS-Chem is a global 3-D chemical transport model (http:// www.geos-chem.org/) which uses detailed inventories for fossil fuel, biomass burning, biofuel burning, biogenic, and aerosol emissions.…”

In this paper the current status of knowledge and research efforts on atmospheric aerosol investigation over Ukraine region are reviewed. Several earlier results of atmospheric extinction, aerosol content and properties studies performed in Ukraine during the second part of the twentieth century are discussed. The recent findings on aerosol optical depth, Ångström exponent, optical and microphysical properties of aerosol particles (single-scattering albedo, size distribution, complex refractive index) and their seasonal variability obtained from both AERONET and portable sun-photometers measurements during the 2008-2016 period are presented and analyzed. Data of POLDER/PARASOL satellite instrument were also involved to study the aerosol properties over Ukraine and neighbor countries. The results showed that aerosol content and properties over Ukraine are very similar to ones over rest European urban regions but considerably lower than over polluted China territories. The first lidar measurements and the air quality evaluations by the PM concentration measurements in Ukraine are also discussed. The aerosol sources in Ukraine and surrounding territories are considered from analysis of the air mass back trajectory and simulation by GEOS-Chem model. The future satellite project Aerosol-UA for global aerosol studies by measurements of the scattered solar radiation polarization is discussed in the article.
