When is air pollution at its worst in Merritt?
Merritt sees clear seasonal swings in air quality, driven in part by its dry grassland setting in the Nicola Valley. 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 Merritt 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.
