Applicazione di un modello fotochimico al bacino aerologico esteso di Milano

This work describes the applications of the quite recent photochemical model CALGRID 1.5 on the wide aerological basin of Milan, which extend for an area of (125×150) km 2 . The week from July 11 to 17 1994 has been chosen as period due to the great amount of data to be processed by the model. The sensitivity analysis has been performed on the base case (July 11/13), paying particular attention to emissions, initial and boundary concentrations variations. Model performances have been evaluated by means of several statistical parameters and graphical procedures. This paper shows the main results obtained.
