Wallingford's position in Oxfordshire means air quality is mostly determined by local road traffic and the compact scale of the centre. Rush-hour queues near the M40 are usually when readings climb the most. Shifting coastal winds do most of the work keeping things in check, more so than any local policy or infrastructure change.

Winter tends to be worst, with wood burning, home heating, and still, cold air trapping traffic fumes from the M40 closer to ground level. Warmer months swap one problem for another — less smoke and heating pollution, but more ozone on the sunniest days. 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 Wallingford 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.
