Abstract

Ozone (O3) is the secondary pollutant formed in the atmosphere through photochemical reactions involving nitrogen oxides and volatile organic compounds in the presence of sunlight. In addition to the chemical and emission variables, a variety of meteorological variables also influence ozone concentrations. Understanding the meteorological parameters (namely temperature, vertical temperature structure, surface winds, aloft winds, local flow patterns, etc) that influence ozone levels is important for selecting variables to help ozone prediction. The selected study area is a typical coastal area located in the middle of Italy. Topography in this area is fairly complex and the proximity to the coast implies a significant interaction between the sea and valley breezes. The climate in this area, in fact, i
