Abstract

Today's environmental impact assessment needs to describe the chemical and physical changes to pollutant concentrations over many hours — not just their dispersion in the atmosphere over the first hour or two. The development of the CSIRO Lagrangian Atmospheric Dispersion Model, LADM, represents a major advance in making adequate assessments. LADM is a synthesis of practical implementations of current scientific knowledge of boundary-layer meteorology, dynamical meteorology in complex geographical regions, plume dynamics, turbulent dispersion in thermally unstable and stable conditions and photochemical smog kinetics. The most startling result from the application of LADM in coastal regions in several studies across Australia is the prevalence of recirculations of pollutants back over
