When is air pollution at its worst in Winnipeg?
Seasonal air quality in Winnipeg is closely linked to its position at the confluence of the Red and Assiniboine rivers, near CentrePort's industrial traffic corridors. Summer humidity can trap pollutants close to the ground during calm stretches, while cold winter nights bring a rise in wood-smoke from home heating. Strong prairie winds usually clear the air within a day or two.
Are air quality levels in Winnipeg 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.
