Local Environmental Conditions
The center of Żory combines built-up streets with more open land, so local traffic matters, though emissions are less concentrated than in a city center. Its setting in the Coal Basin means cold air and pollution can get trapped close to the ground during calm spells. Mining adds to local emissions. Home heating, especially wood stoves and fireplaces, adds smoke and fine particles in the colder months.
Calm, cold weather from November to March, averaging -1°C, lets the basin fill with pollution from home heating and traffic overnight. In the warmer months, summer sun from July to August cooks traffic fumes into ozone, especially in the warmest month, which averages 21°C. On the plus side, breezy weather in January, with winds near 20 km/h, tends to sweep pollution away.

When is air pollution at its worst in Żory?
Calm, cold weather from November to March, averaging -1°C, lets the basin fill with pollution from home heating and traffic overnight. In the warmer months, summer sun from July to August cooks traffic fumes into ozone, especially in the warmest month, which averages 21°C. On the plus side, breezy weather in January, with winds near 20 km/h, tends to sweep pollution away.
Are air quality levels in Żory 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.
Understanding the Scale
The 0–100 air quality scores represent risk levels, not direct air pollutant concentrations. Higher scores indicate higher risk.
Air Quality
| Good | 0-20 | Low air quality risk. Air quality is expected to be good, with low levels of pollution. |
| Fair | 20-40 | Generally low air quality risk. Air quality is expected to be acceptable, with some pollution present. |
| Moderate | 40-60 | Moderate air quality risk. Air pollution is elevated and air quality may be less favorable. |
| Poor | 60-80 | High air quality risk. Air pollution is high and air quality is expected to be poor. |
| Very Poor | 80-100 | Very high air quality risk. Air pollution is very high and air quality is expected to be very poor. |
