In Altus, dry southwestern Oklahoma wind is the main influence on air quality, and cedar pollen in winter and wind-driven dust are the main seasonal concerns. Overall, Altus sees air quality that tracks fairly closely with typical conditions for its wider region. Local topography and prevailing winds both play a role in how quickly conditions change.

When is air pollution at its worst in Altus?
Conditions in Altus vary noticeably across the seasons: a brief stretch in early autumn is often the year's cleanest, once summer ozone season fades, but extended stretches of summer humidity, combined with light winds, tend to bring the worst air of the year. Calm, cold winter spells can occasionally allow local pollution to build up before the next weather system clears it.
Are air quality levels in Altus 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.
