Lac d'Annecy Regatta Centre sees air quality driven largely by valley motorway traffic and light industry, while mountain valley winds alternate with calm temperature inversions, helping maintain reasonable conditions across the year. 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.

Frequently Asked Questions
Is air quality bad in Lac d'Annecy Regatta Centre right now?

When is air pollution at its worst in Lac d'Annecy Regatta Centre?
Lac d'Annecy Regatta Centre is toughest for allergy sufferers when birch and oak pollen peaks and valley motorway traffic and light industry coincide; mountain valley winds alternate with calm temperature inversions, so it doesn't usually last. The presence of alpine valley pasture and orchards in the area adds another layer to the local pattern.
Are air quality levels in Lac d'Annecy Regatta Centre 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.
