In this work the modelling system GAMES is described. It consists of the transport and chemical models CALGRID and TCAM, the meteorological model CALMET, the emission evaluation model POEMPM, the boundary and initial condition module (BICM) and the system evaluation tool (SET). GAMES has two configurations to estimate ozone exposure and to analyze photochemical and aerosols pollution episodes. The system has been designed, implemented and tested over a Northern Italy domain by the Environmental System Modelling and Control research group of Brescia University in the frame of EUROTRAC2-SATURN project
