When is air pollution at its worst in Marpole?
Marpole's air quality shifts noticeably across the seasons, shaped by its position near the mouth of the Fraser River and the airport. Wet winters generally keep the air clean, but summer heat can trap emissions and wildfire smoke within the valley's mountain-ringed basin. Because the surrounding mountains can trap air on hot days, conditions occasionally worsen more here than right on the coast.
Are air quality levels in Marpole 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.
