Commuter traffic feeding onto the A1 adds a further, consistent contribution to local readings.

Easterly winds do most of the work keeping things in check, more so than any local policy or infrastructure change.

Are air quality levels in Botanic Gardens 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.
