P1.12
A fast urban dispersion model - evaluation and application
Rory P. Donnelly, Murdoch University, Perth, Australia; and T. J. Lyons
A fast Lagrangian model for urban pollutant dispersion is presented
and validated against the MUST array data. Model input is limited
to routinely available meteorological data, thus lending the model
to emergency response use. Stabilities and friction velocities
agree well with those derived from on-site 3-D sonic
anemometers. Predicted concentrations agree well with moderate to
high concentration observations, with a mean geometric bias of 1.1
and 84% of predictions within a factor of 2 for arc maxima. Application of the
model to Perth urban area is discussed.
