Air quality in Heathfield is shaped by its location in East Sussex, where vehicle traffic and everyday urban activity dominate local sources. Residential heating and light industry add a modest seasonal contribution, though northwesterly winds off the coast keep overall levels moderate. Traffic on the A34 is the most significant local emissions source, especially at peak times.

When is air pollution at its worst in Heathfield?
Most of spring and autumn stays fairly steady, right in the middle of those two extremes. Air quality in Heathfield isn't the same all year round — it really shifts with the seasons. Winter mornings can be the trickiest, with cold, still conditions trapping A34 traffic fumes and smoke from home fires close to the ground.
Are air quality levels in Heathfield 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.
