Oberhausen's air quality reflects its position at the heart of the Rhine-Ruhr conurbation's former industrial core, with the legacy of steel generating elevated NO₂ and PM2.5. The flat Ruhr basin provides reasonable dispersal, but industrial density in the surrounding conurbation keeps pollution above-average, and the refinery legacy keeps localised background readings elevated.

Is air quality bad in Oberhausen right now?
On 20 September 2026, overall air quality in Oberhausen is fair. AQI is the main air quality indicator at 20.3/100. Pollution peaks around 12:00 PM (NO2: 20.3/100).
Will air quality be worse tomorrow in Oberhausen?
On 21 September 2026, air quality conditions in Oberhausen will be worse than today, with AQI forecast at moderate at 40.8/100. Pollution peaks around 11:00 AM (NO2: 40.8/100).
When is air pollution at its worst in Oberhausen?
Reduced air quality in Oberhausen is most likely when plane, oak, and ash pollen peaks, or on still, humid days when emissions linger locally; regional road traffic is a modest local source. This part of Germany typically experiences only light ragweed levels overall. Breezy days and periods of rain generally bring the clearest conditions.
Are air quality levels in Oberhausen based on measurements or forecasts?
It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
Why doesn’t the forecast always reflect wildfire impacts?
Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.
During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
