By Nordic standards, Kalmar records generally moderate-to-good air quality, with brief exceptions during specific weather patterns. Local sources are dominated by manufacturing and tourism and everyday vehicle traffic rather than any single major industrial emitter. Proximity to the Kalmar Strait facing Öland provides a natural ventilation effect, helping disperse pollutants during most weather conditions. These combined factors give Kalmar air quality that most residents would consider unremarkable in a good way.

When is air pollution at its worst in Kalmar?
How do the seasons affect air quality in Kalmar? Air quality dips are most common in winter, when heating season overlaps with the calm, cold weather that traps local emissions. The changeable spring weather generally keeps pollutant levels lower than in winter, even as pollen becomes more relevant. Summer usually offers the most consistently good air quality, since heating-related emissions drop away almost entirely. Autumn sees a gradual decline from summer's good conditions, as cooler weather brings back wood-smoke and less consistent wind. Being in southern Sweden, temperature swings here are usually less severe, which keeps these seasonal effects fairly moderate.
Are air quality levels in Kalmar 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.
