G-AQFS (Grid Air Quality Forecast System): an experimental system based on GRID computing technologies to forecast atmospheric dispersion of pollutant

Aim of this work is the implementation of an integrated system for modeling air pollutants dispersion using GRID computing technologies. The sys- tem includes two meteorological models, emission pre-processors and two dispersion models for inert and photochemical pollutants. Both meteorological and dispersion models use models which run on the European scale for the initial and boundary conditions. As a test, the modeling system has been applied to the Salento Penin- sula, located in the south-east corner of Italy, in the Mediterranean central area with complex meteorological conditions.
