When is air pollution at its worst in Timmins?
Air quality in Timmins shifts noticeably across the seasons, shaped by gold-mining operations amid vast boreal forest. 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. Dust from mining operations adds a small, steady contribution on top of the seasonal wildfire risk.
Are air quality levels in Timmins 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.
