Worst air pollution Gießen, today and tomorrow

On 21 July 2026, overall air quality in Gießen is fair. AQI is the main air quality indicator at 27.7/100. Pollution peaks around 6:00 PM (O3: 27.7/100).

On 22 July 2026, air quality conditions in Gießen will be similar to today, with AQI forecast at fair at 29.4/100. Pollution peaks around 5:00 AM (NO2: 29.4/100).

In Gießen, reduced air quality is most noticeable when beech, ash, and oak pollen peaks, or during still, humid days when emissions linger locally; typical local traffic patterns add only a modest contribution. Ragweed exposure tends to stay low here through most of late summer. Mornings and breezier days generally bring the clearest conditions.

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.
