Frequent winter chinook winds sweep through and clear the air quickly, while hot, dry summers can bring drifting wildfire smoke from the mountains. Being farther from the downtown core generally keeps conditions a little calmer here than in central Calgary.

Are air quality levels in Okotoks 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.
