When is air pollution at its worst in Corner Brook?
Corner Brook's air quality shifts with the calendar, largely because of its pulp mill on the Bay of Islands in western Newfoundland. 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. Wind direction across the river determines how much of the industrial output drifts into town on any given day.
Are air quality levels in Corner Brook 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.
