Charleroi's air quality faces significant challenges from its position at the heart of the Belgian-French Sambre-Meuse industrial valley, with the legacy steel and chemical industries combined with vehicle traffic on the E42 and surrounding motorway network generating elevated PM2.5 and SO₂. The Sambre valley's topographic enclosure between the Ardennes plateaux and the flat Brabant plain creates concentration of industrial and traffic emissions under frequent calm anticyclonic conditions, making Charleroi one of Belgium's more persistently polluted industrial cities.

When is air pollution at its worst in Charleroi?
Reduced air quality in Charleroi is most likely when oak and birch pollen peaks, alongside periods of the legacy steel and chemical industries; wind and rain both help clear the air fairly quickly here.
Are air quality levels in Charleroi 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.
