Białystok's air quality faces significant winter challenges from residential coal and wood burning in this northeastern Polish city, with the legacy of coal-dependent heating contributing elevated PM2.5 alongside vehicle traffic on the Via Baltica expressway. The flat northeastern Polish plain generally provides reasonable wind dispersal on most days, while the surrounding Podlaskie forests provide a relatively clean regional background compared to the heavily industrialised southwestern Poland airshed.

When is air pollution at its worst in Białystok?
In Białystok, reduced air quality is most noticeable when birch and linden pollen peaks, and on days affected by the legacy of coal-dependent heating; cooler, breezier weather later in the year tends to bring things back down.
Are air quality levels in Białystok 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.
