When is air pollution at its worst in Cranbrook?
Cranbrook sees clear seasonal swings in air quality, driven in part by its position amid the forests of the East Kootenay valley. Air quality is typically excellent for much of the year, though summer weekends bring a rise in vehicle traffic from visitors, and occasional wildfire smoke can drift in during hot, dry stretches. Weekday air quality is often noticeably better than on busy summer weekends when visitor numbers peak.
Are air quality levels in Cranbrook 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.
