The air quality modelling system Pollutants in the Atmosphere and their Transport over Hong Kong (PATH) has been designed to provide guidance on policy and emission controls in Hong Kong. One important air quality objective to be addressed is the annual-average concentration of respirable suspended particulates (RSP). In PATH, this is done by suitably weighting the simulation results from seven case-study...
Simulations of dispersion from an elevated point source in complex terrain and non-stationary flow are presented using the Lagrangian atmospheric dispersion model (LADM, Physick et al., 1992, Air Pollution Modeling and its Applications, Vol. IX, pp. 725-729, Plenum Press, New York; 1994 CSIRO Division of Atmospheric Research Technical Paper No. 24) and the Eulerian grid-based model (CALGRID, Yamartino...
