When is air pollution at its worst in Havre-Saint-Pierre?
Havre-Saint-Pierre's air quality varies through the year, influenced by its remote position on the Côte-Nord shore of the Gulf of St. Lawrence. 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. Because the population is small, local emissions rarely matter as much as what drifts in from distant fires.
Are air quality levels in Havre-Saint-Pierre 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.
