When is air pollution at its worst in Antigonish?
Antigonish sees clear seasonal swings in air quality, driven in part by its position amid the hills of eastern mainland Nova Scotia. Coastal fog and summer humidity are the main features, occasionally trapping local emissions on calm, muggy days, while winter storms off the Atlantic usually keep the air scoured clean. The Atlantic's near-constant weather systems rarely let pollution build up for long.
Are air quality levels in Antigonish 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.
