Seraing's air quality faces significant challenges as the former heart of the Liège Meuse industrial valley, with the ArcelorMittal Liège steel operations legacy and the surrounding chemical and manufacturing industry generating elevated PM2.5 and industrial background alongside vehicle traffic on the E42 motorway. The Meuse valley's topographic enclosure concentrates emissions under frequent inversions, making Seraing one of Belgium's more persistently challenging post-industrial air quality environments throughout the year.

When is air pollution at its worst in Seraing?
Residents in Seraing are quickest to notice reduced air quality when oak and birch pollen peaks, or due to the ArcelorMittal Liège steel operations legacy and the neighbouring chemical and manufacturing industry; conditions generally improve once the season shifts and rainfall or stronger winds return.
Are air quality levels in Seraing 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.
