Abstract: This paper presents the boundary-layer parameterisation model which is applied as a meteorological pre-processor by Finnish regulatory dispersion models. The parameterisation scheme is based on the energy-flux method, which evaluates the turbulent heat and momentum fluxes in the boundary layer. We have compared the model predictions with those of the corresponding scheme of Berkowicz and Prahm, using the same synoptic input data. The comparison shows the basic physical differences between these two models. Some numerical results from these two pre-processors differ substantially, while the results for net radiation are statistically nearly identical.
