Winter mornings can be the trickiest, with cold, still conditions trapping A1 traffic fumes and smoke from home fires close to the ground. In summer, ozone can build up on sunny afternoons, though windier, warmer weather usually helps clear traffic-related pollution faster than in winter.
Are air quality levels in Carrickfergus 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.
