Catania's air quality faces the unique challenge of active volcanic emissions from Mount Etna immediately to the northwest, with SO₂ and volcanic ash plumes from the world's most active European volcano adding to vehicle traffic emissions from the surrounding Catania plain. Mediterranean sea breezes from the Ionian Sea provide afternoon ventilation, while Etna's prevailing southwesterly ash dispersal direction means Catania bears the primary urban volcanic emission burden in the region.

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.
