The dominant factor behind Dyersburg's air quality is humid western Tennessee air; fall ragweed pollen brings the year's sharpest spike. None of this is unusual for a place with Dyersburg's particular geography and climate. Local topography and prevailing winds both play a role in how quickly conditions change.

When is air pollution at its worst in Dyersburg?
Dyersburg sees air quality change through the year, as the cleanest conditions usually arrive in winter, once the humid summer ozone season has ended; by contrast, the stickiest, stillest days of midsummer are typically when conditions dip the most. Occasional agricultural or prescribed-burning smoke can add short-lived particulate spikes outside the main summer ozone season.
Are air quality levels in Dyersburg 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.
