For the investigation of pollutant transport, chemical reactions and atmospheric phenomena in the meso-scale and the micro-scale several 3-dimensional numerical models have been developed.
The 3-dimensional non-hydrostatic mesoscale model METRAS calculates meteorological quantities and concentration fields simultaneously. Chemical reactions are calculated with the model MECTM. Both Models may be nested into results of larger-scale models or in itself and can be coupled interactively to a sea-ice model. The 3-dimensional chemistry transport model MECTM employs METRAS results and is used for pollution transport studies. A simplified version of METRAS has been adopted for users and is now available to the public on request as METRAS-PCL.
The micro-scale obstacle resolving non-hydrostatic transport model MITRAS is used to investigate flow and transport regimes within the urban boundary layer. It can be coupled to the obstacle resolving chemistry model MICTM which directly employs results of the microscale meteorology model MITRAS.
The meso-scale and micro-scale models are coupled within the model system M-SYS which can be used for e.g.simulation of concentration in different resolution.
