When is air pollution at its worst in Iles-de-la-Madeleine?
The Îles-de-la-Madeleine's air quality changes through the year largely because of its remote sandy archipelago in the Gulf of St. Lawrence. For much of the year the air is clean and forest-fresh, but summer and early autumn carry real risk of smoke episodes when wildfires burn nearby or further north. Because the population is small, local emissions rarely matter as much as what drifts in from distant fires.
Are air quality levels in Iles-de-la-Madeleine 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.
