Newmarket sits within Suffolk, and its air quality profile is driven mainly by road traffic and the density of the centre. The area's changeable Atlantic weather generally provide reasonable ventilation, keeping levels close to typical UK urban averages for a town this size. Traffic on the A303 is the most significant local emissions source, especially at peak times.

When is air pollution at its worst in Newmarket?

Spring and autumn tend to be the calmer, more moderate stretches by comparison. Ask a local in Newmarket and they'll tell you air quality changes noticeably from season to season. The coldest months usually bring the worst readings, as heating and temperature inversions keep A303 emissions from dispersing normally. Summer brings a different issue — stronger sunlight can push up ozone levels on hot, sunny days, even though traffic pollution itself often disperses more easily.

Are air quality levels in Newmarket 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.
