Szombathely's air quality reflects its position in the flat Vas county plain near the Austrian border in western Hungary, with vehicle traffic on the M86 and the surrounding automotive parts and electronics manufacturing industry contributing local sources. The flat Transdanubian terrain generally allows reasonable wind dispersal, while winter residential heating and temperature inversions contribute seasonal PM2.5 elevation, and Szombathely's westernmost Hungarian position exposes it to relatively cleaner Alpine and Austrian air masses on prevailing westerly wind days.

When is air pollution at its worst in Szombathely?
You're most likely to notice worse air in Szombathely when local tree and grass allergens peaks, or due to vehicle traffic on the M86 and the surrounding automotive parts and electronics manufacturing industry; conditions usually ease once the wet season or windier weather returns.
Are air quality levels in Szombathely 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.
