Rush-hour queues near the A34 are usually when readings climb the most. Bradford-on-Avon sits within Wiltshire, and its air quality profile is driven mainly by road traffic and the density of the centre. Inland breezes from the surrounding countryside offer a degree of natural ventilation, keeping pollution broadly in line with comparable UK towns.

When is air pollution at its worst in Bradford-on-Avon?
Bradford-on-Avon doesn't have one fixed air quality level — it swings between two extremes each year. Come summer, it's ozone rather than particulates that's the bigger concern, especially on still, sunny days. Winter mornings can be the trickiest, with cold, still conditions trapping A34 traffic fumes and smoke from home fires close to the ground. Spring and autumn tend to be the calmer, more moderate stretches by comparison.
Are air quality levels in Bradford-on-Avon 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.
