Rush-hour queues near the A9 are usually when readings climb the most. Being part of Surrey, Haslemere sees an air quality profile that's largely down to traffic and general town-centre activity. Northwesterly winds off the coast 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 Haslemere?
For much of spring and autumn, things settle into a fairly unremarkable middle ground. Ask a local in Haslemere and they'll tell you air quality changes noticeably from season to season. Winter tends to be worst, with wood burning, home heating, and still, cold air trapping traffic fumes from the A9 closer to ground level. Warmer months swap one problem for another — less smoke and heating pollution, but more ozone on the sunniest days.
Are air quality levels in Haslemere 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.
