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.

The network of measuring stations registered in the ISKO database in 2023. The basis for the air quality assessment is the concentrations measured at the monitoring stations. The measurement network is densest in the areas with the highest concentrations of pollutants, but covers the whole Czech Republic. The backbone network of monitoring stations is the National Air Quality Monitoring Network (NAQMN), operated by the CHMI. It includes both stations with an automated monitoring programme (AIM) and stations with a manual monitoring programme (MIM), from which the samples taken are analysed in the laboratories of the CHMI. In many cases, air pollution at one site is monitored simultaneously by both automatic and manual methods. The national network of concentration monitoring is supplemented by monitoring stations of other organisations, whose measurements are also used in the assessment of air quality.

Concentrations measured by all monitoring networks are stored in the AQIS air pollution database. The database contains data from the beginning of measurements, and sulphur dioxide and suspended particulate matter concentrations from the station networks of the CHMI in North Bohemia and Prague from 1971. Accompanying meteorological data, which are measured at a large part of the automated monitoring stations of the CHMI are used for the evaluation of air quality-meteorological relationships, are also stored in the ISKO database. In addition, the ISKO emission database also includes data provided by cooperating institutions. These include the Public Health Institute in Ostrava, the Public Health Institute in Ústí nad Labem, the National Institute of Health, ČEZ, a. s., municipal authorities and other contributors. The database also includes information from the border areas of Slovakia, Germany, Poland and Austria.

Feature layer depicting the location of springs where the observation of yield is performed. In the past, all springs were observed by volunteers. Currently, these springs are still partly monitored in this way, and partly monitored with equipment having a daily measurement frequency. The data are stored in the Central Regime Database of Groundwater which is maintained by the Hydrology Database and Water Budget Department.

Feature layer depicting the location of boreholes observing groundwater level in shallow and deep aquifers. Currently, most of the measuring objects are equipped with automatic stations that record locally or transmit the data. These stations record once a day. Originally, the boreholes were observed by volunteers with a weekly frequency of measurement. Most of new measuring objects were built during the so-called ISPA project. They went into operation in 2007. The data are stored in the Central Regime Database of Groundwater which is maintained by the Hydrology Database and Water Budget Department.

Feature layer with the location of water-gauging stations. Over 90% of measurements are carried out through automatic stations with locally stored records or transmitted records. Discharge is derived from observed water level using rating curves, which are determined based on hydrometric measurements. The data from these stations are stored in the Central Regime Database of Surface Water which is maintained by the Hydrology Database and Water Budget Department.

This data set contains spatial data with biogeographical division of the Czech Republic. This division was elaborated initially for purposes of national and supra-national Ecological Networks. It has its own hierarchy, consisting of both individual and typological biogeographical units. Higher units (biogeographical province, subprovince, and bioregion) are of individual character. Within the territory of the Czech Republic, two biogeographical provinces, four biogeographical subprovinces and 94 biogeographical regions have been distinguished. Hierarchically lower biogeographical units (biochores, group of geobiocoene types) have typological character; their characteristics in English are intended to be published later. All of the biogeographical units - with the exception of the group of geobiocoene types - are elaborated in maps of scale 1:50 000 and are included in this data set.

This dataset of the elevation of the Czech Republic therefore has the unified design with other data created for this INSPIRE theme in frame of whole Europe. Data were derived from the Digital Terrain Model of the Czech Republic – 4th generation (DMR 4G). For compliance with the data specification data were transformed to coordinate reference system ETRS89-TM33N and heigh reference system EVRS. Data are provided in graphic raster format (tiff) with 5 m spatial resolution together with the accompanying information in GML format.
