When is air pollution at its worst in Burlington?
Burlington sees clear seasonal swings in air quality, driven in part by its Lake Ontario shoreline and escarpment parkland. 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 lake often help clear the air more quickly here than in inland neighbourhoods.
Are air quality levels in Burlington 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.
