When is air pollution at its worst in Weyburn?
Conditions in Weyburn shift with the calendar, largely because of its oil-industry wellsites amid the southern prairie. Winter cold snaps can trap emissions near the ground on calm days, while hot, dry summers bring farm dust and a real risk of wildfire smoke drifting in from the north. The flat, exposed landscape means a stiff wind rarely takes long to disperse things.
Are air quality levels in Weyburn 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.
