When is air pollution at its worst in Lillooet?
Lillooet's air quality varies through the year, influenced by its dry canyon setting along the Fraser River. The valley's winter temperature inversions can trap cool, stagnant air and smog close to the ground, while hot, dry summers bring a real risk of wildfire smoke and orchard dust. Wind moving through the valley plays a large role in whether smoke or smog lingers or clears quickly.
Are air quality levels in Lillooet 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.
