Air quality conditions in Sollentuna are usually good, occasionally interrupted by short-lived local spikes. The presence of commuter residential development in the area contributes a modest but steady share of local emissions, compounded by traffic on the main routes through town. Winds off the surrounding lake and forest district north of the city generally keep pollutant concentrations from building up for extended periods. These combined factors give Sollentuna air quality that most residents would consider unremarkable in a good way.

When is air pollution at its worst in Sollentuna?
What is the yearly air quality pattern like in Sollentuna? Winter is usually the toughest stretch, as temperature inversions during still, cold weather trap local wood-burning and vehicle emissions near street level. Spring typically sees fewer stagnant-air episodes, as more frequent wind and rain help disperse local emissions. Air quality is typically strongest in summer, helped by more wind and sunshine, though still days can occasionally push up ozone levels. Conditions gradually shift through autumn, with cooling temperatures reviving wood-burning and calmer nights allowing brief local build-ups. This is a fairly standard seasonal pattern for central Sweden, with a well-defined winter and summer.
Are air quality levels in Sollentuna 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.
