When is air pollution at its worst in High River?
High River sees clear seasonal swings in air quality, driven in part by its position along the Highwood River south of Calgary. Winter's sudden chinook winds can melt snow and clear the air within hours, while summer heat and wildfire smoke drifting from the Rockies occasionally push pollution higher. Being farther from the downtown core generally keeps conditions a little calmer here than in central Calgary.
Are air quality levels in High River 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.
