Zalaegerszeg's air quality reflects the Zala river valley in the western Hungarian Transdanubia, with vehicle traffic on the M76 expressway and the surrounding automotive and manufacturing industry contributing local sources. The Zala hills create topographic variation, while winter residential heating and temperature inversions in the Zala basin contribute seasonal PM2.5 elevation and the western Hungary position generally provides somewhat cleaner Atlantic-influenced airflows than eastern Hungary's more continental winter inversion episodes throughout the year.

When is air pollution at its worst in Zalaegerszeg?
The most noticeable dips in Zalaegerszeg's air quality come when local tree and grass allergens peaks, or because of vehicle traffic on the M76 expressway and the nearby automotive and manufacturing industry; background levels usually settle back down once the season changes.
Are air quality levels in Zalaegerszeg 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.
