Traffic on the A40 is the most significant local emissions source, especially at peak times.

The area's changeable Atlantic weather do most of the work keeping things in check, more so than any local policy or infrastructure change.

The shoulder seasons generally bring the mildest readings of the year.

Are air quality levels in Aberaeron 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.
