When is air pollution at its worst in Edmonton?
Edmonton's air quality varies through the year, influenced by its position along the North Saskatchewan River on the northern prairie. Winter cold snaps can trap vehicle exhaust and heating emissions close to the ground on calm days, while summer heat and drifting wildfire smoke occasionally push pollution higher. Strong prairie winds usually clear the air within a day or two.
Are air quality levels in Edmonton 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.
