Blacksburg's air quality benefits from the elevated New River Valley position at 644 metres in the Virginia Appalachians, with vehicle emissions from US-460 and the Virginia Tech campus contributing relatively modest local sources. The surrounding Appalachian ridge and valley topography creates seasonal variation, while the mountain setting and the university's research character generally maintain better conditions than comparable Virginia urban areas and summer biogenic ozone is the primary warm-season concern.

Are air quality levels in Blacksburg 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.
