Worst air pollution Zenica, today and tomorrow

On 9 August 2026, overall air quality in Zenica is fair. O3 is the main pollutant at 36.4/100. Pollution peaks around 2:00 AM (NO2: 40.4/100).

On 10 August 2026, air quality conditions in Zenica will be similar to today, with PM1 forecast at fair at 33.9/100. Pollution peaks around 6:00 AM (NO2: 50.8/100).

The clearest dips in Zenica's air quality track hornbeam and oak pollen peaks and periods of steel-industry emissions trapped by the enclosed valley; the rest of the year typically brings clearer, more consistent conditions for the Bosnia and Herzegovina, Federation of area, particularly once autumn winds set in and the local terrain ventilates more easily than during calmer stretches.

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.

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.
