Worst air pollution Guymon, today and tomorrow

On 9 August 2026, overall air quality in Guymon is fair. O3 is the main pollutant at 35.3/100. Pollution peaks around 11:00 PM (NO2: 50.1/100).

On 10 August 2026, air quality conditions in Guymon will be similar to today, with PM1 forecast at fair at 30.5/100. Pollution peaks around 1:00 AM (NO2: 55.0/100).

Guymon's air quality follows a clear seasonal pattern. In short, spring and autumn tend to bring the cleanest, most stable air, whereas the hottest, most humid summer days bring the year's worst ozone readings. Calm, cold winter spells can occasionally allow local pollution to build up before the next weather system clears it.

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.
