Meribel's air quality is shaped mainly by valley motorway traffic and light industry, with its position near the Isere playing a role, while mountain valley winds alternate with calm temperature inversions, which provides a natural check on pollution build-up. Winter is typically the worst season, as cold air settles in the valleys and traps traffic and heating emissions for days at a time; summer sees better dispersion but occasional ozone build-up in the lower valleys.

Is air quality bad in Meribel right now?
On 9 August 2026, overall air quality in Meribel is fair. AQI is the main air quality indicator at 33.7/100. Pollution peaks around 6:00 PM (O3: 33.7/100).

When is air pollution at its worst in Meribel?
In Meribel, allergy sufferers and those sensitive to pollution both notice more symptoms when valley motorway traffic and light industry coincides with heavy birch and oak pollen; mountain valley winds alternate with calm temperature inversions, keeping bad spells relatively short.
Are air quality levels in Meribel 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.
