The study investigates the performance of different air pollution dispersion models in wind calm conditions. The models have been applied to two case studies: the cities of Modena and Reggio Emilia, both placed in the Po river valley (Northern Italy), an area characterized by prevailing weak winds conditions. The emission sources are the municipal waste incinerator of Modena and the Turbo Gas plant of Reggio Emilia. Total suspended particulate (TSP) concentration levels are estimated by three models: the gaussian Industrial Source Complex (ISC3) and WinDimula 3.0 models, and the langrangian particle model SPRAY. The performances of the models have been compared: ISC3 provides less reliable results, while SPRAY and WinDimula 3.0 have shown a good capability to describe a domain characterized by wind calm conditions and SPRAY simulation performs significantly better in the vicinity of the source.

Abstract
The study investigates the performance of different air pollution dispersion models in wind calm conditions. The models have been applied to two case studies: the cities of Modena and Reggio Emilia, both placed in the Po river valley (Northern Italy), an area characterized by prevailing weak winds conditions. The emission sources are the municipal waste incinerator of Modena and the Turbo Gas plant of Reggio Emilia. Total suspended particulate (TSP) concentration levels are estimated by three models: the gaussian Industrial Source Complex (ISC3) and WinDimula 3.0 models, and the langrangian particle model SPRAY. The performances of the models have been compared: ISC3 provides less reliable results, while SPRAY and WinDimula 3.0 have shown a good capability to describe a domain characterized by wind calm conditions and SPRAY simulation performs significantly better in the vicinity of the source.
