Arles's air quality benefits from the Camargue Rhône delta position, with the Mistral wind periodically delivering powerful clean air from the north providing some of France's most dramatic natural ventilation events. Vehicle traffic on the A54 motorway and surrounding agri-food and tourism operations are the primary local sources, while the flat Camargue wetland landscape and the Mistral's frequent occurrence generally maintain Arles among the Languedoc-Provence region's more moderately ventilated urban environments on most days.

When is air pollution at its worst in Arles?
In Arles, the combination of tourist traffic and coastal industry and heavy plane and pine pollen in spring is what most affects sensitive groups; the Mistral wind provides powerful periodic ventilation, so poor conditions rarely last more than a couple of days.
Are air quality levels in Arles 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.
