Developments in Short Range Atmospheric Dispersion Modelling

This short review briefly describes some of the developments in the 1990s of practical and regulatory models for short range atmospheric dispersion. We cover the recent research results on the Atmospheric Boundary Layer and on the spatial and time dependence of atmospheric flows in complex terrain including the structure of turbulence. We consider the consequences of these developments and the better understanding of atmospheric chemistry processes for improved dispersion and transformation of pollutants. Finally some outstanding issues are mentioned about future application and methodologies.
