In Big Stone Gap, clean Appalachian mountain air is the main influence on air quality, and the enclosed valley can trap haze on still summer days. Overall, Big Stone Gap sees air quality that tracks fairly closely with typical conditions for its wider region. Wind direction on any given day can shift things noticeably from the seasonal norm.

When is air pollution at its worst in Big Stone Gap?
Big Stone Gap's air quality has a clear seasonal rhythm, as winter generally brings the cleanest air, once the summer ozone season has passed; by contrast, summer heat waves bring the highest ozone risk, compounded by pollution drifting in from the wider region. Proximity to major highway corridors tends to matter more here than season alone.
Are air quality levels in Big Stone Gap 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.
