Abstract
SUPREME, a very articulated project still in progress financed by the Italian Universities and Research Ministry, concern an integrated decision support system finalized to catastrophic events forecast and to prevent and mitigate esondation and air pollution effects on monumental stones. This paper focuses on the aerosols deposition tool. The Eulerian new box model AERBOX simulates the whole life cycle of aerosols and the consequent urban pollution impact due to the flux of particulate matter deposition. Applied on the monumental area of Florence downtown, AERBOX models the industrial and mobile sources of the 50 km x 50 km surrounding area induced pollution, and estimates the aerosol deposition on a user chosen grid. AERBOX takes into account all the relevant chemical and physical processes involved. Concentration and deposition rates of 52 species of gaseous pollutants and 14 species of particulate pollutants are calculated on hourly basis.The time and chemical profiles of the emissions have been adapted to the Florentine region from the reference profiles given by both California Air Resource Board and EPA. The input data have been interfaced to the model with a user-friendly graphical pre-processor. AERBOX calculates concentrations and deposition fluxes in typical summer and winter seasons and it estimates the effects of cumulated deposition on the monuments. Coupled with a post processor visualisation tool, this system can be seen as an useful tool in urban air pollution management and monitoring.
