Lourdes experiences air quality shaped by tourist and motorway traffic, in a setting close to the Aude, and the Tramontane wind provides periodic ventilation, which helps maintain reasonable air quality across the year. Hot, calm summer spells bring the greatest risk of ozone build-up, while winter is typically cleaner thanks to more frequent Tramontane winds.

When is air pollution at its worst in Lourdes?

In Lourdes, allergy sufferers and those sensitive to pollution both notice more symptoms when tourist and motorway traffic coincides with heavy plane and oak pollen; the Tramontane wind provides periodic ventilation, keeping bad spells relatively short.

Are air quality levels in Lourdes 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.
