The air quality picture in Witney reflects a typical Oxfordshire town, with traffic emissions and local commercial activity as key contributors. Thanks to inland breezes from the surrounding countryside, pollution rarely lingers for long, which keeps average readings fairly unremarkable by UK standards. The M9 generates consistent traffic-related NO₂ and PM2.5, particularly during peak commuting hours.

When is air pollution at its worst in Witney?
In Witney, pollution levels don't stay flat — winter and summer look pretty different. The coldest months usually bring the worst readings, as heating and temperature inversions keep M9 emissions from dispersing normally. By summer, ozone tends to rise on bright days, while better ventilation generally keeps particulate and NO₂ levels lower than winter. For much of spring and autumn, things settle into a fairly unremarkable middle ground.
Are air quality levels in Witney 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.
