Virtual height dispersion model: evaluation against tracer data in different turbulent regimes

摘要

The Virtual Height Dispersion Model is an air quality dispersion model developed to evaluate ground level concentrations from tall stacks (Rizza et al.). It relies on a new gaussian formulation proposed by Lupini & Tirabassi~2 for transport and diffusion in the Atmospheric Boundary Layer (ABL). In that formulation, the real source height is replaced by a virtual height related through wind and eddy diffusivity profiles to stability conditions of ABL. A performance evaluation of the model to different turbulent regimes was performed with tracer data from some experimental field campaigns.
