Osijek's air quality reflects the flat Slavonian Drava-Drava river plain in eastern Croatia, with vehicle traffic on the A5 motorway and surrounding agricultural processing and manufacturing industry contributing local sources. Winter residential wood and coal burning generates elevated PM2.5, while the flat Pannonian plain generally allows reasonable wind dispersal on most days and temperature inversions in the Drava valley concentrate emissions seasonally.

When is air pollution at its worst in Osijek?
Osijek residents notice reduced air quality mainly when oak and linden pollen peaks, and during spells of vehicle traffic on the A5 motorway and local agricultural processing and manufacturing industry; the picture usually improves again once the season turns.
Are air quality levels in Osijek 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.
Why doesn’t the forecast always reflect wildfire impacts?
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.
