When is air pollution at its worst in Centre Videotron?
Centre Vidéotron sees clear seasonal swings in air quality, driven in part by its setting near Quebec City's ExpoCité grounds. The warmest months typically see the poorest air quality, with heat and heavy traffic driving up smog levels on windless days, whereas fall and winter tend to bring cleaner, more variable conditions. Breezes off the St. Lawrence River help disperse pollutants more quickly here than in inland areas.
Are air quality levels in Centre Videotron 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.
