Positioned in the enclosed Jiu valley basin in the Carpathians, Petroşani experiences air quality shaped chiefly by coal-mining legacy emissions trapped by the mountain basin. The Hunedoara terrain plays a role in how pollutants move through the area, with breezier conditions typically dispersing emissions faster than the still, settled spells that let them accumulate.

When is air pollution at its worst in Petroşani?
The clearest dips in Petroşani's air quality track oak and hornbeam pollen peaks and periods of coal-mining legacy emissions trapped by the mountain basin; the rest of the year typically brings clearer, more consistent conditions for the Hunedoara area, particularly once autumn winds set in and the local terrain ventilates more easily than during calmer stretches.
Are air quality levels in Petroşani 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.
