Worst air pollution Essen, today and tomorrow

On 21 July 2026, overall air quality in Essen is fair. AQI is the main air quality indicator at 27.1/100. Pollution peaks around 5:00 PM (O3: 27.1/100).

On 22 July 2026, air quality conditions in Essen will be similar to today, with AQI forecast at fair at 21.7/100. Pollution peaks around 3:00 PM (O3: 21.7/100).

Air quality dips in Essen mostly track maple, plane, and ash pollen peaks and calm, hot days when local sources build up; regional road traffic is a modest local source. Ragweed exposure stays modest in this part of Germany through late summer. Clearer conditions generally arrive on breezier, wetter days.

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.

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.
