Worst air pollution Bar-le-Duc, today and tomorrow

On 21 July 2026, overall air quality in Bar-le-Duc is fair. AQI is the main air quality indicator at 34.7/100. Pollution peaks around 5:00 PM (O3: 34.7/100).

On 22 July 2026, air quality conditions in Bar-le-Duc will be similar to today, with AQI forecast at fair at 32.6/100. Pollution peaks around 2:00 PM (O3: 32.6/100).

For people sensitive to both pollen and pollution in Bar-le-Duc, spring days combining cross-border industry and river traffic with the oak and hornbeam peak are the ones to watch; the Vosges and river valleys shape local wind patterns, which tends to clear things fairly quickly.

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.
