Local Environmental Conditions
With buildings covering much of the area around the heart of Rzeszów, traffic and other urban emissions are the biggest local influence on air quality. Lying in the Sandomierz Basin, the area is prone to temperature inversions that hold pollutants near the ground when winds drop. Local sources include traffic on the A4 motorway and manufacturing.
From November to March, cold air settles into the basin on calm nights and traps emissions from home heating and traffic near the ground; temperatures average about -1°C. Ozone is the main concern from July to August, when sunny days averaging 21°C turn traffic and other emissions into ozone by mid-afternoon. Breezy weather in January, with winds near 20 km/h, tends to sweep pollution away.

When is air pollution at its worst in Rzeszów?
From November to March, cold air settles into the basin on calm nights and traps emissions from home heating and traffic near the ground; temperatures average about -1°C. Ozone is the main concern from July to August, when sunny days averaging 21°C turn traffic and other emissions into ozone by mid-afternoon. Breezy weather in January, with winds near 20 km/h, tends to sweep pollution away.
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.
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. |
