Ilinden's air quality reflects its position in the Vardar valley immediately east of Skopje, with vehicle traffic on surrounding roads and the municipality's light industrial and warehousing operations contributing local sources. Winter residential wood burning generates elevated PM2.5 under valley inversions, while the surrounding hills that ring the Skopje basin concentrate emissions during calm winter periods.

When is air pollution at its worst in Ilinden?
Ilinden residents notice reduced air quality mainly when local tree and grass pollen peaks, and during spells of vehicle traffic on local roads and the municipality's light industrial and warehousing operations; the clearest air tends to follow a change in wind direction or rainfall here.
Are air quality levels in Ilinden 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.
