When is air pollution at its worst in Hippodrome de Trois-Rivieres?
The Hippodrome de Trois-Rivières's air quality follows a seasonal rhythm tied to its riverside setting amid the city's pulp-and-paper mills.

Residents closer to the industrial waterfront tend to notice the seasonal swing more sharply than those higher up.
Are air quality levels in Hippodrome de Trois-Rivieres 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.
