Avellino's air quality reflects the Sabato river valley in the Campanian Apennines at 348 metres, with vehicle traffic on the A16 motorway and surrounding manufacturing and urban operations contributing local sources. The surrounding Irpinia Apennine mountains create significant topographic enclosure, while winter temperature inversions in the valley concentrate heating and vehicle emissions and the Campanian regional background influences the broader Avellino basin air quality under prolonged anticyclonic conditions throughout the year.
