The A1 sees the heaviest traffic, and that shows up clearly in local roadside monitoring. Being part of Bradford, Keighley sees an air quality profile that's largely down to traffic and general town-centre activity. Onshore breezes tend to disperse pollutants reasonably well, keeping readings close to typical UK small-town levels.

When is air pollution at its worst in Keighley?
Air quality in Keighley isn't the same all year round — it really shifts with the seasons. Winter tends to be worst, with wood burning, home heating, and still, cold air trapping traffic fumes from the A1 closer to ground level. Summer sunshine can drive up ozone locally, though overall air generally moves and clears more freely than in winter. Spring and autumn are typically the easiest months, air-quality-wise, for most residents.
Are air quality levels in Keighley 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.
