When is air pollution at its worst in Riviere-des-Prairies-Pointe-aux-Trembles?
In Rivière-des-Prairies–Pointe-aux-Trembles, air quality changes through the year largely because of its east-end industrial waterfront along the Rivière des Prairies. Warmer months usually bring elevated ozone and haze as heat, sunlight and vehicle emissions interact, while cooler months bring a marked improvement, apart from occasional temperature inversions that trap pollutants near the surface overnight. Its distance from the island's dense core usually keeps conditions a little calmer than central Montréal.
Are air quality levels in Riviere-des-Prairies-Pointe-aux-Trembles 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.
