Air quality in Andover is shaped by its location in Hampshire, where vehicle traffic and everyday urban activity dominate local sources. Thanks to northwesterly winds off the coast, pollution rarely lingers for long, which keeps average readings fairly unremarkable by UK standards. Emissions along the M74 represent the town's main traffic-related pollution source.

When is air pollution at its worst in Andover?
Spring and autumn usually sit somewhere in between, so it's really the extremes of the year worth watching. Seasons make a real difference to air quality in Andover, more than most people realise. The coldest months usually bring the worst readings, as heating and temperature inversions keep M74 emissions from dispersing normally. Summer's more of a mixed bag: ozone can spike in strong sun, but overall dispersion tends to be better than the depths of winter.
Are air quality levels in Andover 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.
