Vancouver's air quality in Washington State reflects the Portland metropolitan area's Willamette Valley position, with vehicle emissions from I-5 generating concentrated commuter traffic across the Columbia River Bridge and wood-burning stoves contributing winter PM2.5. Summer wildfire smoke from Oregon and Washington forests is an increasingly severe seasonal concern, while the valley's partial topographic enclosure between the Coast Range and Cascades concentrates emissions under temperature inversions on calm days.

When is air pollution at its worst in Vancouver?
Air quality in Vancouver shifts across the year, as the wet winter and spring months are generally the cleanest, with regular rain limiting particulate buildup; by contrast, late summer wildfire smoke is the biggest concern, sometimes pushing air quality into unhealthy territory for days at a stretch. Coastal areas see relatively little of the smoke that can settle into inland valleys during fire season.
Are air quality levels in Vancouver 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.
