Reșița's air quality reflects the Bârzava river valley in the Banat mountains of western Romania, with the former steel and mining industrial complex generating historical heavy metal and SO₂ legacy alongside current vehicle traffic on the DN58. The surrounding Semenic and Anina mountains create significant topographic enclosure, while winter inversions concentrate vehicle and heating emissions and the industrial legacy maintains elevated background metal particulate levels.

When is air pollution at its worst in Reşiţa?
Reşiţa residents notice reduced air quality mainly when oak and beech pollen peaks, and during spells of the former steel and mining industrial complex; a change of season or a spell of wind usually clears things up again.
Are air quality levels in Reşiţa 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.
