Fountainebleau's air quality in France benefits from the Forêt de Fontainebleau's extensive woodland covering 25,000 hectares to the southeast of Paris, with the forest providing exceptional natural filtration and buffering from Paris metropolitan emissions. Vehicle traffic on the A6 motorway and tourism operations are the primary local sources, while the UNESCO-protected forest's clean-air influence and the Fontainebleau palace setting generally maintain some of the Seine-et-Marne département's better urban air quality conditions throughout the year.

When is air pollution at its worst in Fountainebleau?
Fountainebleau's air quality has a clear seasonal rhythm, as the wet season's frequent storms generally keep particulate levels lower than in the dry months; by contrast, without the wet season's regular storms, dry-season smoke can linger for days at a time. Sea breezes help disperse pollution on most days, though smoke from inland fires can still drift into populated areas.
Are air quality levels in Fountainebleau 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.
