INVESTIGATION OF INHALABLE AEROSOL DISPERSION AT CUBATÃO BY MEANS OF A MODELING SYSTEM FOR COMPLEX TERRAIN
摘要
A modeling system, consisting of the mesoscale model RAMS (Regional Atmospheric Modeling System), the Lagrangian dispersion model SPRAY, and the interface code MIRS (Model for Interfacing RAMS and SPRAY), has been used to numerically investigate the dispersions of inhalable particulate matter emitted by fertilizer plants located at Cubatao (Brazil). RAMS produced the wind fields on the basis of large scale meteorological analysis; MIRS prepared the turbulence statistics field and transformed the RAMS output into SPRAY inputs; SPRAY also computed the concentration field. The results of these simulations were compared with the source apportionment performed by chemical mass balance on samples of aerosol collected during previous field campaigns.
