Commuter traffic feeding onto the A96 adds a further, consistent contribution to local readings. Chippenham sits within Wiltshire, and its air quality profile is driven mainly by road traffic and the density of the centre. The region's typical south-westerlies tend to disperse pollutants reasonably well, keeping readings close to typical UK small-town levels.

When is air pollution at its worst in Chippenham?
Spring and autumn are typically the easiest months, air-quality-wise, for most residents. Ask a local in Chippenham and they'll tell you air quality changes noticeably from season to season. Once the heating goes on and the air turns still, pollution from the A96 and nearby chimneys tends to build up rather than clear. Come summer, it's ozone rather than particulates that's the bigger concern, especially on still, sunny days.
Are air quality levels in Chippenham 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.
