Worst air pollution Shenandoah, today and tomorrow

On 30 August 2026, overall air quality in Shenandoah is moderate. AQI is the main air quality indicator at 40.2/100. Pollution peaks around 11:00 AM (O3: 40.2/100).

On 31 August 2026, air quality conditions in Shenandoah will be better than today, with AQI forecast at fair at 31.0/100. Pollution peaks around 11:00 AM (O3: 31.0/100).

Shenandoah experiences a distinct seasonal swing in air quality. In short, the cleanest stretch of the year usually comes in winter, whereas the peak of summer humidity, combined with heavy traffic corridors nearby, brings the sharpest dip. Suburban and rural areas generally see less of the persistent traffic-driven pollution that affects the urban core.

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.

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.
