When is air pollution at its worst in Riviere-du-Loup?
Riviere-du-Loup's air quality follows a seasonal rhythm tied to its bluff-top setting above the widening St. Lawrence estuary. Air quality is generally good, though spring and fall fieldwork stir up dust and occasional agricultural burning, and summer humidity can trap haze close to the ground. Away from the main roads, air quality generally stays good even during the busier farming months.
Are air quality levels in Riviere-du-Loup 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.

Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
