Kerpen's air quality faces challenges from the Hambacher Forst lignite open-cast mine — one of Europe's largest — and the surrounding RWE coal power stations generating elevated SO₂ and PM2.5 alongside traffic on the A4. The flat Rhine-Erft basin provides reasonable dispersal, while the lignite operations' scale makes Kerpen one of Germany's most mining-defined urban areas.

When is air pollution at its worst in Kerpen?
In Kerpen, the days to watch are when linden, ash, and oak pollen peaks, or hot, still days when local emissions build up; day-to-day road traffic here stays a fairly minor, steady source. This part of Germany typically experiences only light ragweed levels overall. Windier afternoons generally bring noticeably clearer air than calm mornings.
Are air quality levels in Kerpen 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.
