When is air pollution at its worst in Stumholmen?
Does air quality in Stumholmen vary by season? Cold, still winter days are when pollutant levels are most likely to climb, mainly from heating and traffic rather than any single major source. The changeable spring weather generally keeps pollutant levels lower than in winter, even as pollen becomes more relevant. Most of the year's best readings occur in summer, with only rare hot, calm days causing a temporary rise in ground-level ozone. The transition into autumn typically brings a slow return of the wood-smoke and calm-air conditions that peak in winter. The comparatively mild southern Swedish climate means these seasonal swings are usually less pronounced than further north.
Are air quality levels in Stumholmen 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.
