Air quality in Duncan is driven mostly by open southwestern Oklahoma wind — cedar pollen in winter is the year's sharpest local event. Overall, Duncan sees air quality that tracks fairly closely with typical conditions for its wider region. Wind direction on any given day can shift things noticeably from the seasonal norm.

When is air pollution at its worst in Duncan?
Duncan follows a fairly predictable seasonal air quality pattern — late spring tends to offer some of the most reliably clean air, before summer heat sets in, whereas summer heat waves are the main driver of poor air quality, as ozone builds under stagnant, humid conditions. Fast-moving weather systems typical of the region usually keep pollution from lingering too long.
Are air quality levels in Duncan 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.
Why doesn’t the forecast always reflect wildfire impacts?
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.
