Dispersion models used and developed
|
ALLSTAR |
('ALL Stability Random walk dispersion model'). A Lagrangian stochastic particle dispersion model, which is correct, i.e. fulfils the well-mixed condition') for all stabilities from fully convective to stable stratification. Developed in-house.

OML |
The Danish operational (Gaussian) plume dispersion model. The model is mainly used over urban surfaces, for which circumstances a modification (OML-URB) has been developped and tested.
