Worst air pollution Bremen, today and tomorrow

On 21 July 2026, overall air quality in Bremen is fair. AQI is the main air quality indicator at 23.9/100. Pollution peaks around 5:00 PM (O3: 23.9/100).

On 22 July 2026, air quality conditions in Bremen will be better than today, with AQI forecast at good at 19.8/100. Pollution peaks around 10:00 AM (O3: 19.8/100).

Residents in Bremen are most likely to notice reduced air quality when willow, linden, and ash pollen peaks, or on warm, windless days when local pollution accumulates; ordinary road use nearby adds a small but steady source. The sea's moderating effect keeps ragweed exposure consistently low in this area. Calm, still days tend to bring the least comfortable conditions overall.

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.
