What is the yearly air quality pattern like in Himmelstalund Sports Ground? Winter inversions are the main seasonal risk, occasionally trapping smoke and traffic fumes for a day or two during especially calm, cold spells. Spring's changeable weather tends to prevent the kind of stagnant air that causes winter pollution episodes. The year's most consistently good air usually falls in summer, when heating season has ended and ventilation improves. As the clocks change, so does the air quality pattern, with wood-smoke and calmer nights gradually taking over from summer's cleaner air. As is typical for this part of the country, the seasonal contrast here is clear but not extreme.

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.

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.
