Air data

Several times a day measuring stations of the German Environment Agency (UBA) and the German States measure data on ambient air quality in Germany. Shortly after the measurement you can use Germany-wide maps and graphs to get informed about currently measured values and forecasts. Further you can find air quality data sorted by station of the past years.

Please note: current data represent preliminary values which are subject to change due to quality assurance. Back dated values are successively replaced by quality assured values.

Air quality index

How good is the air? Our air quality index shows you. It is based on hourly average measurements of ozone (O3), nitrogen dioxide (NO2), particulate matter (PM10 and PM2.5) and sulphur dioxide (SO2). Using the latest hourly values from a station, pollutant concentrations are classified into five index classes from "very good" to "very poor" with the aid of threshold values. The pollutant with the worst rating determines the AQI classification and thus the index class and colour. More information on the index calculation you can get in the calculation base.
