Årdalstangen is the industrial town in Årdal municipality on the Årdalsfjord, with vehicle traffic and the Hydro Årdal aluminium plant generating elevated industrial PM2.5 and fluoride alongside local sources. The fjord valley creates topographic concentration under calm conditions, while fjord breezes provide periodic ventilation and the aluminium smelter represents the most distinctive local air quality contribution throughout the year.

When is air pollution at its worst in Årdalstangen?
The period residents in Årdalstangen notice most on the calmest, coldest days of winter, when cold air pools in the steep valley on the rare calm, dry day. The region's famously high rainfall usually washes the air clean again quickly. Otherwise, Årdalstangen maintains good air quality across most of the calendar.
Are air quality levels in Årdalstangen 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.
