Zgierz's air quality reflects the flat Łódź industrial metropolitan area in central Poland, with vehicle traffic on the S14 expressway and the surrounding textile and manufacturing legacy industry contributing local sources. Winter residential coal and wood burning generates elevated PM2.5, while the flat central Polish plain provides reasonable dispersal and the Łódź metropolitan area's regional pollution background consistently influences the air quality environment throughout the year.

Is air quality bad in Zgierz right now?
On 9 August 2026, overall air quality in Zgierz is fair. AQI is the main air quality indicator at 32.9/100. Pollution peaks around 2:00 AM (NO2: 32.9/100).

When is air pollution at its worst in Zgierz?
The most noticeable dips in Zgierz's air quality come when local tree and grass allergens peaks, or because of vehicle traffic on the S14 expressway and the neighbouring textile and manufacturing legacy industry; a shift to wetter or windier weather typically brings noticeable relief.
Are air quality levels in Zgierz 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.
