Emissions along the M90 represent the town's main traffic-related pollution source.

When is air pollution at its worst in Leith?
Spring and autumn usually sit somewhere in between, so it's really the extremes of the year worth watching. Leith doesn't have one fixed air quality level — it swings between two extremes each year. Winter mornings can be the trickiest, with cold, still conditions trapping M90 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 Leith 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.
