Development and Verification of a New
Meteo-Dispersive Modelling System
for Accidental Releases in the Italian
Territory: SMART
Andrea Bisignano, Silvia Trini Castelli and Piero Malguzzi
Abstract A new modelling system, SMART, is under development for the simulation of accidental releases dispersion. The interfacing code ARAMIS was originally created to interface the non-hydrostatic atmospheric model MOLOCH and
the Lagrangian stochastic dispersion model SPRAY. Here, a comparison between
simulations with the new modelling suite SMART and the RMS modelling system,
applied in several previous assessment studies, is presented for a case of a release in
complex terrain in southern Italy. The new suite is planned to be adopted as a tool
for emergency response purposes in any part of the Italian territory at any time.
13.1 Introduction
At the CNR-ISAC daily numerical forecasts are issued, by applying the meteorological models developed by the MODAT modelling group. The forecasts are produced in support of research on the atmospheric circulation and composition and
in order to test and improve the meteorological models operating from the global
to the local scales. At the regional scale and for the full Italian territory, MOLOCH
model is producing forecasts with high spatial detail, grid size of 1.25 km, integrating
the non-hydrostatic, fully compressible equations for the atmosphere (http://www.
isac.cnr.it/dinamica/projects/forecasts/moloch/). Given the availability of these highresolution forecasts, we developed a new interface, ARAMIS, between MOLOCH
and the Lagrangian particle dispersion model SPRAY, and tested it in some case
studies in different sites of Italy. The final goal is to build a modelling suite that
can forecast the dispersion of possible accidental releases in any part of the Italian
territory at any time.
