Worst air pollution Canyonlands National Park - Moab, today and tomorrow

On 9 August 2026, overall air quality in Canyonlands National Park is fair. AQI is the main air quality indicator at 34.9/100. Pollution peaks around 9:00 AM (O3: 34.9/100).

On 10 August 2026, air quality conditions in Canyonlands National Park will be similar to today, with AQI forecast at fair at 37.6/100. Pollution peaks around 9:00 AM (O3: 37.6/100).

This landmark in Moab sees air quality shift through the year, as autumn is often the cleanest stretch, between wildfire season and the onset of winter inversions; by contrast, valley and basin locations can see pollution trapped under cold air for days during winter inversions. Valley and basin locations are especially prone to these winter inversion episodes compared to more exposed, higher terrain.

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.
