Abstract

Modelling Atmospheric Transport, Dispersion and Deposition on Short and Long Range Validation against ETEX-1 and ETEX-2, and Chernobyl A contribution to subproject GLOREAM Annemarie Bastrup-Birk, J0rgen Brandt and Zahari Zlatev National Environmental Research Institute, Department of Atmospheric Environment, Frederiksborgvej 399, P.O. Box 358, DK-4000 Roskilde, Denmark The model system The comprehensive, three-dimensional tracer model, DREAM (the Danish Rimpuff and Eulerian Accidental release model, see Brandt, 1998; Brandt et ai, 1996b; 1996c; 1998; Bastrup-Birk et al, 1998), is used to study transport, dispersion, and deposition of air pollution caused by a single but strong source, as e.g. the Chernobyl accident. The model is based on a combination of two-dimensional versions of a Lagrangian short-scale puff model (RIMPUFF, Thykier-Nielsen and Mikkelsen, 1993) and an Eulerian long-range transport model (the Danish Eulerian Model, Zlat
