Abstract

Monitoring performed at the environmental network stations of Ravenna, a city along northern Italy's Adriatic seaboard, shows that the breeze-driven transport of air masses markedly contributes to the pollution levels. The time evolution of photochemical oxidants along the coast is strongly influenced by the breeze circulation in summer, when primary pollutants are transported offshore by the land-breeze, undergo photochemical transformations at sea and are driven back inshore by the sea breeze, resulting in high concentration values of photochemical oxidants at the ground. A mass-budget approach was applied to determine the roles played by chemistr
