On 22 July 2026, air quality conditions in Heidenheim an der Brenz will be better than today, with AQI forecast at medium at 52.3/100. Pollution peaks around 4:00 AM (NO2: 52.3/100).

You're most likely to notice worse air in Heidenheim an der Brenz when chestnut, ash, and oak pollen peaks, or on windless summer days when pollutants accumulate nearby; traffic passing through town adds a modest local contribution. Ragweed levels rise modestly from mid-August, consistent with much of southern Germany. Afternoon breezes usually clear out any buildup from the morning.

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.
