Air quality data sources
Trace measurements, forecasts and map geography back to their providers and see how each source is used.
European Environment Agency
European station data comes from records reported by national authorities and distributed by the EEA. Recent records can be provisional. The verified archive provides a separate basis for historical assessment. Station and city pages show the data type, time and quality information available for each result.
Station measurements are credited to the European Environment Agency and the reporting networks. The European AQI bands come from the EEA. The agency publishes material under a Creative Commons Attribution licence unless otherwise indicated. Check the specific dataset for exceptions and third-party rights before reuse.
Copernicus Atmosphere Monitoring Service and Open-Meteo
Contains modified Copernicus Atmosphere Monitoring Service information provided through Open-Meteo. The forecasts include CAMS European ENSEMBLE and global atmospheric composition products where available. PiSpace Air selects, formats and labels the values for display and computes European AQI categories from eligible concentrations.
The regional and global grids differ in spacing and native time steps. Pollen is seasonal and supported in the European product. See each panel for the data source, period and available model metadata.
Open-Meteo publishes its API data under CC BY 4.0 and has separate access terms for its free API. The CAMS dataset records list the applicable product licences and citations. The European Commission and ECMWF are not responsible for how the Copernicus information on this site is used.
Place names and map boundaries
The location catalogue uses names and coordinates drawn from GeoNames and reviewed local records. GeoNames makes its geographical database available under a Creative Commons attribution licence.
Made with Natural Earth public-domain geography. The base maps are simplified to show broad geographic context. Markers refer to catalogue places or monitoring stations. Country and territory boundaries follow the source dataset.
PiSpace Air selects GeoNames entries for the location catalogue and uses local names and aliases for search. Before redistributing place or map data, use the attribution and terms provided by the original dataset.
