Traffic on the A38 is the most significant local emissions source, especially at peak times. Air quality in Wokingham is shaped by its location in Wokingham, where vehicle traffic and everyday urban activity dominate local sources. Onshore breezes usually ensure decent dispersal, so levels generally stay within the moderate range typical of UK towns.

When is air pollution at its worst in Wokingham?
Wokingham doesn't have one fixed air quality level — it swings between two extremes each year. Come winter, NO₂ and PM2.5 usually creep up, as heating and calmer air let A38 traffic emissions linger rather than disperse. Come summer, it's ozone rather than particulates that's the bigger concern, especially on still, sunny days. Most of spring and autumn stays fairly steady, right in the middle of those two extremes.
Are air quality levels in Wokingham 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.
