Worst air pollution Bretten, today and tomorrow

On 21 July 2026, overall air quality in Bretten is fair. O3 is the main pollutant at 33.2/100. Pollution peaks around 11:00 PM (NO2: 42.4/100).

On 22 July 2026, air quality conditions in Bretten will be similar to today, with O3 forecast at fair at 37.2/100. Pollution peaks around 1:00 AM (NO2: 46.1/100).

Air quality dips in Bretten mostly track maple, oak, and ash pollen peaks and still, humid days when emissions linger locally; typical local traffic patterns add only a modest contribution. From mid-August, a modest ragweed presence typically appears in this warmer region. The clearest air tends to arrive after rain or on breezy afternoons.

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.
