Mons' air quality reflects the Belgian Hainaut industrial corridor, with vehicle traffic on the E19 and A7 motorways and the surrounding former coal mining and manufacturing legacy generating elevated PM2.5 alongside residential heating. The flat Walloon plateau provides reasonable dispersal on most days, while cross-border pollution from the French Nord-Pas-de-Calais industrial area and the Charleroi corridor elevates background pollution above typical Belgian urban averages.

Are air quality levels in Mons 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.
