When is air pollution at its worst in Mariebergsskogen?
How does air quality change throughout the year in Mariebergsskogen? Air tends to be least fresh in deep winter, when household heating and traffic emissions get trapped under still, cold air masses. Conditions usually start improving from March as wind and rain become more frequent, helping clear out whatever built up over winter. Warm-season conditions are generally the most favourable of the year, with wood-burning emissions largely absent. As autumn progresses, damp, still evenings can occasionally trap emissions before winter's more persistent inversions set in. This pattern is fairly typical for central Sweden, where all four seasons are clearly distinct.
Are air quality levels in Mariebergsskogen 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.
