Air quality in Stroud is shaped by its location in Gloucestershire, where vehicle traffic and everyday urban activity dominate local sources. Rush-hour queues near the A38 are usually when readings climb the most. Northwesterly winds off the coast usually ensure decent dispersal, so levels generally stay within the moderate range typical of UK towns.

Come winter, NO₂ and PM2.5 usually creep up, as heating and calmer air let A38 traffic emissions linger rather than disperse. Warmer months swap one problem for another — less smoke and heating pollution, but more ozone on the sunniest days. Spring and autumn tend to be the calmer, more moderate stretches by comparison.

Are air quality levels in Stroud 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.
