Nyíregyháza's air quality reflects the flat Great Hungarian Plain of northeastern Hungary, with vehicle traffic on the M3 motorway and surrounding agri-food and pharmaceutical manufacturing contributing local sources. Winter residential heating and temperature inversions on the open Hungarian plain contribute seasonal PM2.5 elevation, while the eastern Hungary position creates moderate continental air quality conditions throughout the year.

When is air pollution at its worst in Nyíregyháza?
In Nyíregyháza, reduced air quality is most noticeable when canal network oak and linden pollen peaks, and on days affected by vehicle traffic on the M3 motorway and surrounding agri-food and pharmaceutical manufacturing; wind and rain both help clear the air fairly quickly here.
Are air quality levels in Nyíregyháza 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.
