When is air pollution at its worst in Portage la Prairie?
Portage la Prairie's air quality changes through the year largely because of the Simplot potato plant and Highway 1 traffic. Winter cold snaps can trap local emissions near the ground on calm days, while hot, dry summers bring farm dust and a real risk of wildfire smoke drifting in from further afield. Strong, steady prairie winds usually clear the air within a day or two of any buildup.
Are air quality levels in Portage la Prairie 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.
