European Air Quality Index (hourly measures)

- European Air Quality Index (based on pollutant concentrations in µg/m³): hourly measurements for all pollutants for the most recent time for each station - Sub-indexes O3, PM10, PM2.5, NO2, and SO2 are available according to the type of stations (industrial, bottom or traffic) in accordance with the methodology for calculating the European air quality index by measuring stations throughout the Greater Region - Depth of data: The most recent index of the last 3 hours for each station is available every hour. If the calculation of the index is not possible due to lack of data its value marked by a grey pellet in the symbology of the map (data not available). In the absence of measurement of certain pollutants (missing sub-indexes), the overall index is still calculated on the basis of the pollutants measured at the station concerned - Data sources: Atmo Grand Est; Agence Wallonne de l’Air et du Climat — AWAC; Landesamt für Umwelt- und Arbeitsschutz Saarland — IMMESA; Landesamt für Umwelt Rheinland-Pfalz — Zimen; Environmental Administration Luxembourg.
