When is air pollution at its worst in Musee de la civilisation?
The Musée de la civilisation's air quality is closely linked to its riverside setting in Old Quebec. Warmer months usually bring elevated ozone and haze as heat, sunlight and vehicle emissions interact, while cooler months bring a marked improvement, apart from occasional temperature inversions that trap pollutants near the surface overnight. Breezes off the St. Lawrence River help disperse pollutants more quickly here than in inland areas.
Are air quality levels in Musee de la civilisation 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.
