In Old Washington Historic District, light traffic and open farmland nearby mean seasonal dust and burning outweigh congestion as a pollution source here. The nearest mapped tree cover is about 3150 meters off, too far to meaningfully filter this particulate load here. Local monitoring for the wider area tends to track closely with this general pattern.

When is air pollution at its worst in Old Washington Historic District?
The depths of winter usually mark the low point for local air quality, as rural heating sources add up under inversions that keep smoke from dispersing. Summer heat pushes ozone to the forefront of local air quality concerns, as warm, sunny conditions drive ozone formation, sometimes worsened by smoke from distant wildfires. Between the winter and summer extremes, spring and fall usually bring the year's most consistently clear air.
Are air quality levels in Old Washington Historic District 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.
