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.

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.
