Design and validation of a multiphase 3D model to simulate tropospheric pollution

Secondary pollutant production and removal are non linear processes, driven by precursor emissions, solar radiation and meteorological conditions. The study of these processes and the evaluation of the impact that suitable emission control strategies can have in a certain domain, require the implementation of deterministic mathematical models solving chemical/transport differential equation systems. This work presents the Transport and Chemical Aerosol Model (TCAM) and its validation over a Northern Italy domain, performed processing yearly simulations concerning 1999. The model assessment analysis underlines that the model is adequately reliable to describe the atmospheric chemistry in a complex domain and that it can be used to estimate the impact of secondary pollution control strategies.
