Being part of Warwickshire, Atherstone sees an air quality profile that's largely down to traffic and general town-centre activity. Commuter traffic feeding onto the A47 adds a further, consistent contribution to local readings. Southwesterly winds generally provide reasonable ventilation, keeping levels close to typical UK urban averages for a town this size.

When is air pollution at its worst in Atherstone?
In Atherstone, pollution levels don't stay flat — winter and summer look pretty different. Through the colder months, readings near the A47 often rise, since chimney smoke and stagnant air stop pollutants clearing away. Summer's more of a mixed bag: ozone can spike in strong sun, but overall dispersion tends to be better than the depths of winter. Spring and autumn tend to be the calmer, more moderate stretches by comparison.
Are air quality levels in Atherstone 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.
