Silverton experiences air quality conditions shaped chiefly by high-altitude mountain air, and among the cleanest air in Colorado, aside from occasional wildfire smoke. Most days bring generally favorable conditions here, with occasional exceptions tied to shifting weather patterns. Visitors and residents alike tend to notice the clearest air outside the warmest summer weeks.

When is air pollution at its worst in Silverton?
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.
Why doesn’t the forecast always reflect wildfire impacts?
Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.
During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
