When is air pollution at its worst in Charlottetown?

Charlottetown's air quality rises and falls with the seasons, shaped by its harbourside setting amid Prince Edward Island's farmland. The Atlantic's damp, changeable weather usually keeps the air clean, apart from the odd still, humid summer day when local emissions linger a little longer. The Atlantic's near-constant weather systems rarely let pollution build up for long.

Are air quality levels in Charlottetown 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.
