When is air pollution at its worst in Edmundston?
Seasonal air quality in Edmundston is closely linked to its pulp mill along the Saint John River in northwestern New Brunswick. Air quality is generally very good outside of wildfire season, though hot, dry summers can bring smoky, hazy stretches when fires burn across the wider region. Wind direction across the river determines how much of the industrial output drifts into town on any given day.
Are air quality levels in Edmundston 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.
