Abstract

Development and application of a long- term atmospheric dispersion model for environmental impact assessment purposes F. Desiato", R. Inghilesi^ ^National Environmental Protection Agency Instituto di Fisica, Universitd 'La Sapienza', Rome, Italy ABSTRACT The computer code AMETISTA has been developed for evaluating the long- term air pollution caused by emissions from more co-located sources. The aim is to have an updated and flexible tool for estimating air concentration levels caused by actual or hypothetical routine emissions, and for comparing them with the air quality standards prescribed for different sampling times and reference periods. AMETISTA is applied in the framework of the ANPA support activity to the Commission of Environmental Impact Assessment of the Italian Minister of the Environment. The code is divided into a Meteorological Preprocessor, an Atmospheric Diffusion module mostly based on the HPDM model (Hanna and Chang [1]), and a Statistical Postpr
