Šentilj's air quality reflects its position in the Mura river valley on the Slovenian-Austrian border, with vehicle traffic from the busy A1 motorway border crossing and surrounding agricultural land contributing local sources. Winter residential wood burning adds seasonal PM2.5, while the open Mura valley generally allows better dispersal than more enclosed Slovenian valleys, keeping conditions moderate for most of the year.

When is air pollution at its worst in Šentilj?
Šentilj residents notice reduced air quality mainly when local combined tree and grass pollen peaks, and during spells of vehicle traffic from the busy A1 motorway border crossing and nearby agricultural land; the rest of the calendar year is generally more forgiving for air quality.
Are air quality levels in Šentilj 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.
