Worst air pollution Dillon, today and tomorrow

On 9 August 2026, overall air quality in Dillon is fair. O3 is the main pollutant at 37.4/100. Pollution peaks around 12:00 AM (NO2: 59.4/100).

On 10 August 2026, air quality conditions in Dillon will be similar to today, with O3 forecast at fair at 34.1/100. Pollution peaks around 3:00 PM (NO2: 54.6/100).

Dillon's air quality follows a clear seasonal pattern, as the shoulder seasons of spring and fall typically offer the most stable, cleanest conditions; by contrast, summer brings regional wildfire smoke, while winter brings its own inversion-driven pollution episodes. Higher-elevation, more exposed locations generally avoid the worst of the valley inversion episodes.

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.
