Abstract

Dispersion modelling during licensing procedures is, due to the limited time frame, a rather challenging task. Complex building structures or source configurations, which call for sophisticated dispersion models require usually long computation times. A new modelling tool for such applications has been developed in Austria, which is based on simulations for 34 pre-defined source configurations using the Lagrangian Particle Model GRAL (Graz Lagrangian Model). Annual mean, maximum daily mean, and maximum hourly concentrations can be calculated within a few seconds/minutes. The model is already approved by the Austrian ministry and is made available free of charge.
