When is air pollution at its worst in Ballymena?
Ask a local in Ballymena and they'll tell you air quality changes noticeably from season to season. Summer sunshine can drive up ozone locally, though overall air generally moves and clears more freely than in winter. Come winter, NO₂ and PM2.5 usually creep up, as heating and calmer air let A1 traffic emissions linger rather than disperse. Spring and autumn are typically the easiest months, air-quality-wise, for most residents.
Are air quality levels in Ballymena 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.
