When is air pollution at its worst in Grotte de Saint-Elzear?
The Grotte de Saint-Elzéar's air quality is closely linked to its remote cave setting on the Gaspé Peninsula. Winters here typically bring the cleanest air of the year, but summer and early fall can bring sharp, sometimes prolonged drops in air quality when wildfire smoke drifts in from across the region. Its isolation means most seasonal change here comes from regional weather and smoke rather than local sources.
Are air quality levels in Grotte de Saint-Elzear 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.
