Abstract
Tropospheric ozone is a considerable part of the atmospheric pollution, mainly in summer period. Its formation is driven by photochemical reactions in presence of high temperature and intense sunlight.
Under these conditions ozone precursors, such as oxides of nitrogen (NOx) and volatile organic compounds (VOC), undergo oxidizing reactions. Not only is the formation of tropospheric ozone influenced by precursors coming from antropogenic sources, emissions from natural sources, especially in remote areas, have their importance as well.
Numerical model for simulation and evaluation of summer photochemical smog episodes was used for studying the terms of formation, amount and spatial distribution of tropospheric ozone in the north-eastern part of the Czech Republic. Model results were compared with measured data.
