When is air pollution at its worst in Oak Bay?
Oak Bay sees clear seasonal swings in air quality, driven in part by its leafy seaside streets east of downtown Victoria. Winter brings frequent rain that keeps the air clean and washed, while summer's drier stretches can occasionally trap traffic emissions and, in bad wildfire years, smoke drifting in from the BC Interior. Persistent onshore breezes off the Pacific generally keep pollutants from building up for long.
Are air quality levels in Oak Bay 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.
