Leirvik is the main town in Stord municipality on the Hardangerfjord approach island, with vehicle traffic and the significant offshore platform construction and industrial corridor generating elevated industrial PM2.5. Consistent North Sea maritime breezes provide coastal ventilation, while the offshore construction represents the most distinctive local air quality contribution throughout most of the year.

When is air pollution at its worst in Leirvik?
In Leirvik, air quality dips are most noticeable during the height of the spring pollen season, when a rare dry, calm spell can let pollen levels build up in the fjord basin. The area's wet, windy climate generally keeps background air quality high. Beyond these episodes, Leirvik's air quality generally stays favourable.
Are air quality levels in Leirvik 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.
Why doesn’t the forecast always reflect wildfire impacts?
Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.
During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
