Worst air pollution Herrenberg, today and tomorrow

On 21 July 2026, overall air quality in Herrenberg is fair. AQI is the main air quality indicator at 32.6/100. Pollution peaks around 7:00 PM (O3: 32.6/100).

On 22 July 2026, air quality conditions in Herrenberg will be similar to today, with NO2 forecast at fair at 25.0/100. Pollution peaks around 4:00 PM (O3: 40.4/100).

The most noticeable dips in Herrenberg's air quality come when maple, ash, and chestnut pollen peaks, or on warm, windless days when local pollution accumulates; regional road traffic is a modest local source. A modest ragweed presence typically develops here from mid-August, as in much of southern Germany. 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.
