Intercomparison of Lagrangian dispersion models and validation with Lillestrom data
Three different Lagrangian models (KLIMM-L, LASAT and STOER.LAG) are applied to the Lillestrom datasets. A pre-processing of the required vertical wind-profiles unifies the flow fields for the three models. In the framework of harmonisation the models show partial agreement with the datasets. The discrepancies are the same for all models. One reason for deviation of the datasets might be locally induced heat turbulence by domestic heating, which was not accounted for in the modelling approach.
