St Ives sits within Cornwall, and its air quality profile is driven mainly by road traffic and the density of the centre. Easterly winds usually ensure decent dispersal, so levels generally stay within the moderate range typical of UK towns. The A470 generates consistent traffic-related NO₂ and PM2.5, particularly during peak commuting hours.

When is air pollution at its worst in St Ives?
There's a clear yearly cycle to air quality in St Ives if you look closely. The coldest months usually bring the worst readings, as heating and temperature inversions keep A470 emissions from dispersing normally. Warmer months swap one problem for another — less smoke and heating pollution, but more ozone on the sunniest days. Most of spring and autumn stays fairly steady, right in the middle of those two extremes.
Are air quality levels in St Ives 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.
