When is air pollution at its worst in Estevan?

Air quality in Estevan shifts noticeably across the seasons, shaped by its coal-fired power plants in the southeastern prairie. Cold winter days can trap local heating emissions close to the ground, while summer heat, farm dust and occasional wildfire smoke can push pollution higher than usual. The flat, exposed landscape means a stiff wind rarely takes long to disperse things.

Are air quality levels in Estevan 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.
