Abstract
Data on the surface ozone concentrations measured at six coastal stations in Bulgaria, Greece, Montenegro, and Russia are compared. Seasonal and diurnal ozone cycles are analyzed for each station. It is shown that differences in ozone regimes are connected with microclimatic and topographic features of the stations, distance from the sea, and level of anthropogenic pollution. High ozone episodes are considered. It is shown that the large-scale ozone episode in the late summer of 2011 was a result of the prolonged abnormal weather, and high ozone concentrations (160-200 μg × m-3) were formed in plumes of ozone precursors arrived from territories of Caspian gas and oil developments.
