When is air pollution at its worst in Abergavenny?
For much of spring and autumn, things settle into a fairly unremarkable middle ground. Abergavenny's air quality follows a familiar seasonal pattern most UK towns share. Winter tends to be worst, with wood burning, home heating, and still, cold air trapping traffic fumes from the A55 closer to ground level. Summer's more of a mixed bag: ozone can spike in strong sun, but overall dispersion tends to be better than the depths of winter.
Are air quality levels in Abergavenny 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.
