Like much of Oxfordshire, Didcot's air quality is shaped less by industry these days and more by everyday road traffic. Thanks to inland breezes from the surrounding countryside, pollution rarely lingers for long, which keeps average readings fairly unremarkable by UK standards. Rush-hour queues near the M6 are usually when readings climb the most.

When is air pollution at its worst in Didcot?
Didcot's air quality follows a familiar seasonal pattern most UK towns share. 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. Once the heating goes on and the air turns still, pollution from the M6 and nearby chimneys tends to build up rather than clear. Spring and autumn don't usually cause much concern, sitting comfortably between winter's peak and summer's ozone spikes.
Are air quality levels in Didcot 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.
