Salisbury sits within Wiltshire, and its air quality profile is driven mainly by road traffic and the density of the centre. Thanks to the dominant maritime airflow, pollution rarely lingers for long, which keeps average readings fairly unremarkable by UK standards. Rush-hour queues near the M3 are usually when readings climb the most.

When is air pollution at its worst in Salisbury?
Salisbury's air quality follows a familiar seasonal pattern most UK towns share. 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. The coldest months usually bring the worst readings, as heating and temperature inversions keep M3 emissions from dispersing normally. For much of spring and autumn, things settle into a fairly unremarkable middle ground.
Are air quality levels in Salisbury 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.
