INSPIRE – Air quality model areas
Concentrations of air pollutants in the 1x1 km grid, year 2023. Limit values for the protection of human health SO2 - 4th highest 24-hour SO2 concentration [µg.m-3], PM10 - annual average concentration [µg.m-3], PM10 - 36th highest 24-hour average concentration [µg.m-3], PM2.5 - annual average concentration [µg. m-3], NO2 - annual average concentration [µg.m-3], O3 - 26th highest maximum daily 8-hour moving average concentration averaged over 3 years, 2019-2021 [µg.m-3], As - annual average concentration [ng.m-3], Cd - annual average concentration [ng.m-3], benzo[a]pyrene - annual average concentration [ng.m-3], benzene - annual average concentration [µg.m-3]. Areas with exceedances of limit values without O3. Areas with exceedances of the limit values with the inclusion of O3. Limit values for the protection of ecosystems and vegetation O3 - AOT40 exposure index values, 5-year average, 2019-2023 [µg.m-3], NOx - annual average concentration [µg.m-3], SO2 - annual (annual average) and winter period (winter average) [µg.m-3].
Legislation (Act 201/2012 Coll., as amended) requires that the primary source of assessment be the results of stationary measurements. Measured concentrations may be supplemented by modelling and indicative measurements in the production of pollutant maps to ensure that the resulting estimate provides sufficient information on the spatial distribution of air pollutant concentrations. In the Czech Republic, the Eulerian chemical dispersion model CAMx is mainly used, additionally also the Gaussian model SYMOS and the European Eulerian model EMEP. In addition, in the case of individual pollutants, e.g. altitude or population density.
