Fort Madison's air quality is driven largely by a combination of vehicle traffic, seasonal heating, and nearby land use. Vegetation near Big Bureau Creek and within Rock Run Rookery Preserve offers a measure of natural filtering for the surrounding air. Wind direction and seasonal weather patterns drive much of the day-to-day variation seen here.

When is air pollution at its worst in Fort Madison?
The coldest months tend to bring Fort Madison's worst particulate levels, as heating demand and traffic settle in under stagnant winter air. By summer, ground-level ozone becomes the bigger issue, as intense heat and sunlight drive photochemical smog. Drifting wildfire smoke from farther away sometimes adds to the summer air quality burden. Spring and fall, with milder temperatures and steadier wind, generally offer the cleanest air of the year.
Are air quality levels in Fort Madison 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.
