Przemyśl's air quality reflects the San river valley in the southeastern Polish Subcarpathian highlands near the Ukrainian border, with vehicle traffic on the S19 expressway and the surrounding manufacturing and logistics industry contributing local sources. Winter residential wood and coal burning generates elevated PM2.5, while the surrounding Carpathian foothills create topographic variation and cold valley inversions can concentrate heating and vehicle emissions during winter anticyclonic periods.

When is air pollution at its worst in Przemyśl?
Residents in Przemyśl are most likely to notice reduced air quality when oak and linden pollen peaks, or due to vehicle traffic on the S19 expressway and the local manufacturing and logistics industry; wind and rain both help clear the air fairly quickly here.
Are air quality levels in Przemyśl 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.
