Trollhättan's air quality is generally good by Swedish standards, with the Göta river corridor providing consistent ventilation and the surrounding lake district maintaining relatively clean background conditions in this major automotive manufacturing city. Vehicle traffic on the E45 motorway and the Saab/NEVS and surrounding automotive manufacturing operations contribute the primary local sources, while the Göta river's open water fetch and consistent westerly airflows generally maintain Trollhättan among Sweden's more moderate automotive-industrial urban environments.

When is air pollution at its worst in Trollhättan?
How do the seasons affect air quality in Trollhättan? Air quality is typically at its weakest in December and January, when cold, calm, high-pressure spells let wood-smoke and traffic exhaust settle close to the ground instead of dispersing. Spring typically sees fewer stagnant-air episodes, as more frequent wind and rain help disperse local emissions. The summer months tend to be the least problematic, aside from the occasional heatwave that can nudge ozone levels upward. Autumn is a transitional period: as the heating season resumes in September and October, occasional calm evenings can again trap wood-smoke locally. As is typical for this part of the country, the seasonal contrast here is clear but not extreme.
Are air quality levels in Trollhättan 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.
