In Belfort, light industry and river-valley traffic is the primary local source affecting air quality, near the Yonne, while the Saone and Doubs valleys channel airflow, which provides a natural check on pollution build-up. Winter brings the worst air quality, as calm, cold conditions trap heating and traffic emissions in the river valleys; summer is generally cleaner, though occasional heatwaves can push ozone levels up.

When is air pollution at its worst in Belfort?
In Belfort, the combination of light industry and river-valley traffic and heavy oak and hornbeam pollen in spring is what most affects sensitive groups; the Saone and Doubs valleys channel airflow, so poor conditions rarely last more than a couple of days. The presence of Burgundy vineyards and cereal plains in the area adds another layer to the local pattern.
Are air quality levels in Belfort based on measurements or forecasts?
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.
