The Euralille area of Lille experiences air quality driven by former coalfield industry and motorway traffic, while North Sea winds sweep across the open plains, keeping conditions reasonable across the year. Cold, still winter weather is the main risk for particulate build-up, while summer usually benefits from stronger regional winds, aside from occasional ozone episodes.

When is air pollution at its worst in Euralille?
Euralille, within Lille, sees its worst combined pollen and air quality days when former coalfield industry and motorway traffic coincide with the spring birch and oak peak; North Sea winds sweep across the open plains.
Are air quality levels in Euralille 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.
