Ross-on-Wye's air quality reflects its position within Herefordshire, with local traffic and the town's built-up core as the main contributors. The nearby A82 corridor contributes steady vehicle emissions that affect roadside readings. Thanks to cooler northerly winds, pollution rarely lingers for long, which keeps average readings fairly unremarkable by UK standards.

When is air pollution at its worst in Ross-on-Wye?
Seasons make a real difference to air quality in Ross-on-Wye, more than most people realise. Summer brings a different issue — stronger sunlight can push up ozone levels on hot, sunny days, even though traffic pollution itself often disperses more easily. Winter tends to be worst, with wood burning, home heating, and still, cold air trapping traffic fumes from the A82 closer to ground level.
Are air quality levels in Ross-on-Wye 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.
