Rezumat: As an active photo-oxidant the atmospheric ozone can cause serious damages to human health and vegetation – forests, crops. That is why the ozone studies are of primary importance for adequate formulation of the environmental policy of the country. A set of integral ozone characteristics (ozone indices) has been developed, which make it possible the ozone pollution impact on human health and ecosystems to be quantitatively evaluated. Calculation and analysis of these ozone indices for Bulgaria are the overall goals of the present work. The US EPA Models-3 system is chosen as a modelling tool. As the NCEP Global Analysis Data with 1 degree resolution is used as meteorological background, the MM5 and CMAQ nesting capabilities are applied for downscaling the simulations to a 9 km resolution over Balkans and 3 km over Bulgaria. The TNO emission inventory is used as emission input. Special pre-processing procedures are created for introducing temporal profiles and speciation of the emissions. The study is based on a large number of numerical simulations carried out day by day for years 2000-2007.
