Oslo's Majorstuen records moderate inner Oslo air quality in this busy junction district, with the tram interchange and the Ring 2 road corridor generating sustained local emissions. The Frognerparken park to the west provides a clean-air buffer that improves conditions on the park-facing side of this inner west Oslo neighbourhood.

When is air pollution at its worst in Majorstuen?
The main air quality concern in Majorstuen arises during short stretches of calm winter weather, when temperature inversions over the built-up area trap emissions close to street level. Regional wind patterns off the Oslofjord usually clear the air within a day or two. For the rest of the year, Majorstuen typically sees consistently good air quality.
Are air quality levels in Majorstuen 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.
