Commuter traffic feeding onto the M5 adds a further, consistent contribution to local readings. Bicester sits within Oxfordshire, and its air quality profile is driven mainly by road traffic and the density of the centre. Residential heating and light industry add a modest seasonal contribution, though inland breezes from the surrounding countryside keep overall levels moderate.

When is air pollution at its worst in Bicester?
Spring and autumn usually sit somewhere in between, so it's really the extremes of the year worth watching. You can roughly predict Bicester's air quality just by knowing the time of year. The coldest months usually bring the worst readings, as heating and temperature inversions keep M5 emissions from dispersing normally. Warmer months swap one problem for another — less smoke and heating pollution, but more ozone on the sunniest days.
Are air quality levels in Bicester 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.
