Rzeszów's air quality faces winter challenges from residential coal and wood burning generating elevated PM2.5 alongside vehicle traffic on the A4 motorway in this rapidly growing southeastern Polish technology and aviation hub. The Subcarpathian foreland's partial enclosure between the Carpathian foothills to the south and the Sandomierz Basin to the north creates modest topographic variation, while Rzeszów's growing aeronautical and manufacturing base contributes industrial emissions alongside the seasonal coal heating burden.

When is air pollution at its worst in Rzeszów?
Residents in Rzeszów are most likely to notice reduced air quality when oak and birch pollen peaks, or due to residential coal and wood burning; a shift to wetter or windier weather typically brings noticeable relief.
Are air quality levels in Rzeszów 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.
