Abstract

An Eulerian model for passive gas dispersion based on the K-theory for turbulent diffusion, coupled with a mass
consistent wind model is presented. The procedure can be used to forecast gas concentration over large and complex
terrains. The input to the model includes the topography, wind measurements from meteorological stations,
atmospheric stability information and gas flow rate from the ground sources. Here, this model is applied to study
the distribution of the CO2 discharged from the hot sources of the Solfatara Volcano, Naples, Italy, where the input
data were measured during a 15 day campaign in June 2001 carried out to test an Eddy Covariance (EC) station
by Osservatorio Vesuviano-INGV, Naples.
