ABSTRACT
In this paper the traffic pollution in downtown Macao is investigated by Large Eddy Simulation (LES). The complex building layout is simulated by a composite model that the buildings and streets are properly resolved with fine grids in the residential area and a roughness element model is used for buildings in the surrounding area with coarse grids. The wind field and carbon oxide distribution are computed from 7 am to 5 pm in an autumn day. The numerical results are checked by wind tunnel measurement and field observation with satisfaction.
