When is air pollution at its worst in Regina?
Seasonal air quality in Regina is closely linked to its position on the flat prairie around man-made Wascana Lake. Cold snaps in winter can trap local emissions close to the ground, while summer heat and occasional drought conditions raise the risk of drifting wildfire haze. Open prairie winds usually clear the air within a day or two of any buildup.
Are air quality levels in Regina 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.
