We present numerical results of the boundary layer model used for regulatory purposes in Finland, and compare these with measurements from field campaigns and routine measurements. The parameterisation schemes used in the dispersion models of the Finnish Meteorological Institute (FMI) are based on the energy flux method of van Ulden and Holtslag (1985), and the parameterisation of the boundary layer height is based on classical boundary layer models with a separate treatment for convective and stable conditions.
