Applied dispersion modelling for ground level concentration from elevated source

A practical short-range model evaluating ground-level concentrations from elevated sources is presented, which utilizes a Fickian-typeformula, where the source height and mixing layer height are simple functions of the wind velocity and eddy diffusivity profiles. The model performances are evaluated against an exact solution of the advection diffusion equation and against experimental ground-level concentrations, using meteorological data collected near the ground and wind and eddy diffusivity profiles predicted by the Similarity Theory.
