Title: Wind and Eddy Diffusivity Parameterizations for an Operative Air Pollution Model
Abstract: Two parameterizations for wind and eddy diffusivity profiles in the planetary boundary layer (PBL) based on a similarity theory are applied in the operational dispersion model VHDM (Virtual Height Dispersion Model). One is the well known Pleim and Chang parameterization, while the other one is more physically consistent and was applied to an analytical model (as VHDM is) for the first time. The formulations are compared using the data from the Copenhagen experiment and statistical evaluation applying widely used indices showing that the PBL parameterizations are well suited for application in air pollution modelling over the whole unstable atmospheric stability regime.
