The Lombardy airport system is composed by the three international nodes of Malpensa, Linate (respectively the second and the third Italian stopovers) and Orio al Serio (third Italian freight node). They involve almost the 23 % of the totality of the Italian airport departures and approaches. Montichiari airport is included as well: less important than the others, it is assuming a growing strategic role. Thus, airport noise pollution is one of the main issues in the Lombardy environment care framework. It has led to the realization of three noise continuousmonitoring systems in correspondence of the three main airport nodes. In order to face the existing population demand of noise control, the Regional Environmental Protection Agency (ARPA) together with the Lombardy Regional Administration, has set up a specialized technical centre (PTA - Presidio Tecnico Aeroportuale). The main activities and aims are: 1. Monitoring system checking; 2. Elaboration of airport noise impact scenarios; 3. Estimation of population noise exposure. The first one is a technical-instrumental activity. A checklist has been carried out, which allows an effective, systematic evaluation of the airport monitoring activities. As far as modelling activities are concerned, the PTA is currently testing the input data of the INM model computational algorithms, in order to enhance the evaluation of the environmental noise impact and improve the analysis of local scenarios. The exposed population assessment represents a meaningful issue both for the environment and inhabitant's protection, and for regulatory purposes as a valid decisional tool. The PTA is implementing a new land use-based methodology with the application of computational algorithms that can assign different population density weights to territorial areas. Even if recently established, the PTA has achieved encouraging results. The monitoring system checking activities have allowed a reliability improvement, while the noise impact evaluation has led to the optimisation of INM model application. Finally, the development of a reference methodology of the exposed population assessment constitutes a useful and easy to apply regulatory tool This aspect will be the subject of the following paper.
