Greenville's Judson air quality reflects the historic mill village residential neighbourhood, with vehicle traffic on the surrounding Poinsett Highway corridor contributing local sources. The flat Piedmont terrain allows reasonable dispersal, while the neighbourhood's residential character generally maintains moderate Greenville metropolitan readings throughout most of the year.

When is air pollution at its worst in Judson?
Air quality at Judson shifts across the year. Typically, once summer humidity fades, winter typically offers the most consistently clean air, while summer heat, humidity, and emissions from surrounding forests combine to drive ozone levels up. Prescribed burns are more common in the cooler months and can add brief smoke episodes.
Are air quality levels in Judson 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.
