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.

Annual tabulation

The daily mean value of PM₁₀ must not exceed 50 μg/m³ more than 35 times in the calendar year. The annual mean value must not exceed 40 µg/m³. CO levels above 10 mg/m³ (highest daily 8-hour average) must not occur. Ozone levels above 120 μg/m³ (highest daily 8-hour average) should occur on maximum of 25 days of the calendar year, averaged over 3 years. Hourly means above 180 µg/m³ are counted as exceedance of the information threshold, hourly means above 240 µg/m³ are counted as exceedance of the alert threshold. The AOT40 shall not exceed 18,000 µg/m3 ·h (averaged over 5 years). The long-term objective is not to exceed 6,000 µg/m3 ·h per year. Hourly mean values must not exceed 350 μg/m³ more than 24 times in the calendar year. The daily mean value of SO₂ must not exceed 125 μg/m³ more than 3 times in the calendar year. The annual mean value of NO₂ must not exceed 40 µg/m³. Hourly mean values must not exceed 200 μg/m³ more than 18 times in the calendar year. The annual mean value must not exceed 0.5 µg/m³. That corresponds to 500 ng/m³. The annual mean value shall not exceed 1 ng/m³. The annual mean value of benzene must not exceed 5 µg/m³. The annual mean value of PM2.5 must not exceed 25 µg/m³. The annual mean value shall not exceed 6 ng/m³. The annual mean value shall not exceed 5 ng/m³. The annual mean value shall not exceed 20 ng/m³.

* Pursuant to § 20 or § 21 of Directive 2008/50/EC, exceedances of the PM₁₀ daily mean limit value due to natural sources or gritted sand or salt may be deducted by winter road clearance services.

* Passive collectors with monthly mean values cannot record hour overruns due to time resolution.

* AOT40: Accumulated Ozone Exposure over a threshold of 40 ppb. It is the accumulated excess of hourly ozone concentrations above 80 μg/m³ (between 8:00 and 20:00 CET in the growth season).
