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.

When is air pollution at its worst in Mons?
Residents in Mons are likeliest to notice reduced air quality when oak and linden pollen peaks, or due to vehicle traffic on the E19 and A7 motorways and the local former coal mining and manufacturing; the clearest air tends to follow a change in wind direction or rainfall here.
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.
Why doesn’t the forecast always reflect wildfire impacts?
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.
