Worst air pollution Vesoul, today and tomorrow

On 21 July 2026, overall air quality in Vesoul is fair. AQI is the main air quality indicator at 33.4/100. Pollution peaks around 7:00 PM (O3: 33.4/100).

On 22 July 2026, air quality conditions in Vesoul will be similar to today, with O3 forecast at fair at 37.4/100. Pollution peaks around 6:00 AM (NO2: 41.5/100).

In Vesoul, the worst combined pollen and air quality days tend to come when light industry and river-valley traffic coincide with the peak oak and hornbeam pollen season in spring; the Saone and Doubs valleys channel airflow, so conditions usually improve within a day or two. Nearby Burgundy vineyards and cereal plains add a further seasonal factor.

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.
