Commuter traffic feeding onto the A14 adds a further, consistent contribution to local readings. Being part of Hampshire, Fareham sees an air quality profile that's largely down to traffic and general town-centre activity. Onshore breezes do most of the work keeping things in check, more so than any local policy or infrastructure change.

When is air pollution at its worst in Fareham?
Ask a local in Fareham and they'll tell you air quality changes noticeably from season to season. Winter mornings can be the trickiest, with cold, still conditions trapping A14 traffic fumes and smoke from home fires close to the ground. By summer, ozone tends to rise on bright days, while better ventilation generally keeps particulate and NO₂ levels lower than winter. Spring and autumn usually sit somewhere in between, so it's really the extremes of the year worth watching.
Are air quality levels in Fareham 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.
