Villeurbanne's air quality reflects its position as Lyon's most immediate eastern satellite, sharing the Rhône-Alpes basin's enclosed topographic challenge with the additional burden of the concentrated urban and industrial character of the Part-Dieu business district and the surrounding Université Lyon 1 campus traffic. The Rhône river corridor provides limited ventilation, while the surrounding Alpine foothills and Massif Central create the typical enclosed basin conditions that make Lyon and its inner suburbs one of France's more challenging winter air quality environments.

Is air quality bad in Villeurbanne right now?
On 20 September 2026, overall air quality in Villeurbanne is moderate. AQI is the main air quality indicator at 42.3/100. Pollution peaks around 9:00 AM (NO2: 42.3/100).
Will air quality be worse tomorrow in Villeurbanne?
On 21 September 2026, air quality conditions in Villeurbanne will be better than today, with AQI forecast at fair at 28.6/100. Pollution peaks around 6:00 PM (O3: 28.6/100).
When is air pollution at its worst in Villeurbanne?
For people sensitive to both pollen and pollution in Villeurbanne, spring days combining valley motorway traffic and light industry with the birch and oak peak are the ones to watch; mountain valley winds alternate with calm temperature inversions, which tends to clear things fairly quickly. Nearby alpine valley pasture and orchards add a further seasonal factor.
Are air quality levels in Villeurbanne 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.
