Krosno's air quality profile is influenced chiefly by its Wisłok River location, where glass manufacturing beneath the Carpathian foothills and local industrial activity both leave a measurable mark on local readings. The surrounding Podkarpackie landscape generally allows reasonable dispersal on most days, though winter inversions can trap emissions locally.

When is air pollution at its worst in Krosno?
The most noticeable dips in Krosno's air quality come when beech and oak pollen peaks and when glass manufacturing beneath the Carpathian foothills adds to the mix; the picture usually improves again once the season turns and the local weather pattern changes for good.
Are air quality levels in Krosno 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.
