On 21 September 2026, air quality conditions in Les Beaux-Arts will be better than today, with AQI forecast at good at 19.8/100. Pollution peaks around 11:00 AM (PM2.5: 19.8/100).

For those living in Les Beaux-Arts, part of Montpellier, spring days combining tourist and motorway traffic with heavy plane and oak pollen are the hardest; the Tramontane wind provides periodic ventilation, so it rarely lasts long. The presence of Languedoc vineyards and Pyrenean farmland in the area adds another layer to the local pattern.

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.

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.
