The dominant factor behind West Jefferson's air quality is clean high-elevation Blue Ridge air; this is some of the cleanest air quality in the Southeast. None of these influences are extreme on their own, but together they shape the local pattern in West Jefferson. Wind direction on any given day can shift things noticeably from the seasonal norm.

When is air pollution at its worst in West Jefferson?
Seasonal changes shape air quality across West Jefferson, as mild winter weather usually brings the year's cleanest air; by contrast, summer heat combined with the region's dense forest cover drives an extended ozone season. Occasional agricultural or prescribed-burning smoke can add short-lived particulate spikes outside the main summer ozone season.
Are air quality levels in West Jefferson 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.
