Air quality in Ascoli Piceno is shaped mainly by vehicle traffic and residential heating in the enclosed valley, against a backdrop of the Marche landscape in a valley where the Tronto and Castellano rivers meet. Ventilation varies with the terrain, and conditions are typically at their best when weather systems move through more actively, while extended dry, calm periods tend to coincide with the town's least favourable air quality readings.
