When is air pollution at its worst in Altona?
Altona's air quality is closely linked to the Bunge oilseed-crushing plant and Highway 30 traffic. Cold winter days can trap heating emissions close to the ground, while summer heat, farm dust and occasional wildfire smoke can push pollution higher than usual. Strong prairie winds usually clear the air within a day or two, though nearby fields can add dust during planting and harvest.
Are air quality levels in Altona 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.
