The nearby M2 corridor contributes steady vehicle emissions that affect roadside readings. Armagh's air quality reflects its position within Armagh City, Banbridge and Craigavon, with local traffic and the town's built-up core as the main contributors. Shifting coastal winds tend to disperse pollutants reasonably well, keeping readings close to typical UK small-town levels.

When is air pollution at its worst in Armagh?
Spring and autumn are typically the easiest months, air-quality-wise, for most residents. Seasons make a real difference to air quality in Armagh, more than most people realise. Winter mornings can be the trickiest, with cold, still conditions trapping main road traffic fumes and smoke from home fires close to the ground. 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.
Are air quality levels in Armagh 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.
