On 31 August 2026, air quality conditions in Djäkneberget will be similar to today, with AQI forecast at fair at 26.6/100. Pollution peaks around 5:00 PM (O3: 26.6/100).

What is the yearly air quality pattern like in Djäkneberget? Winter is usually the toughest stretch, as temperature inversions during still, cold weather trap local wood-burning and vehicle emissions near street level. Air quality tends to recover through spring as milder, windier conditions replace the still winter air masses. Summer generally brings the year's best air quality, thanks to longer days, more ventilation, and less need for heating. As autumn progresses, damp, still evenings can occasionally trap emissions before winter's more persistent inversions set in. The seasonal swing here is fairly pronounced, typical of central Swedish towns away from the immediate coast.

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.
