When is air pollution at its worst in Rouyn-Noranda?
The air over Rouyn-Noranda varies through the year, influenced by its copper smelter and mining history in the Abitibi region. Air quality is generally very good outside of wildfire season, though hot, dry summers can bring smoky, hazy stretches when fires burn across the wider region. Dust from mining operations adds a small, steady contribution on top of the seasonal wildfire risk.
Are air quality levels in Rouyn-Noranda 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.
