-To do the WRF pre-processing for a real-case simulation getting initial and boundary conditions from ECMWF-IFS data on model levels, you could use a script such as the following. However, it depends on namelists, variable tables and other settings files being correctly specified. See below for details.
+The `met_em*` files linked in this snipped are the outcome of the WRF preprocessing (interpolation of initial and boundary conditions from another model, or from reanalyses, on the WRF grid). The WRF preprocessing system (WPS) is a separate set of executables, that can be built only after WRF is successfully compiled. To run WPS for a real-case simulation, getting initial and boundary conditions from ECMWF-IFS data on model levels, you could use a script such as the following. However, it depends on namelists, variable tables and other settings files being correctly specified. See below for details.
