For most of the year, air quality in Sollefteå sits comfortably within good Swedish and European benchmarks. Hydropower and forestry adds a steady background emission source, on top of the usual traffic through the centre. Wind patterns linked to the Ångermanälven river valley usually keep the air moving enough to prevent prolonged pollution build-up. These combined factors give Sollefteå air quality that most residents would consider unremarkable in a good way.

When is air pollution at its worst in Sollefteå?
When is air quality typically worst in Sollefteå? Winter is usually the toughest stretch, as temperature inversions during still, cold weather trap local wood-burning and vehicle emissions near street level. Spring usually marks a turning point, with more active weather systems reducing how often pollutants can accumulate. Warm-season conditions are generally the most favourable of the year, with wood-burning emissions largely absent. The transition into autumn typically brings a slow return of the wood-smoke and calm-air conditions that peak in winter. Given the longer, colder northern winter, this seasonal swing tends to be more pronounced and longer-lasting than further south.
Are air quality levels in Sollefteå 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.
