Silverton sees air quality change through the year: autumn is often the cleanest stretch, between wildfire season and the onset of winter inversions, but valley and basin locations can see pollution trapped under cold air for days during winter inversions. Valley and basin locations are especially prone to these winter inversion episodes compared to more exposed, higher terrain.
Are air quality levels in Silverton 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.
