Wps

The WRF [1] Preprocessing System (WPS) is a set of three programs whose collective role is to prepare input to the real.exe program for real-data simulations. Each of the programs performs one stage of the preparation: geogrid defines model domains and interpolates static geographical data to the grids; ungrib extracts meteorological fields from GRIB-formatted files; and metgrid horizontally interpolates the meteorological fields extracted by ungrib to the model grids defined by geogrid. The work of vertically interpolating meteorological fields to WRF eta levels is now performed within the real.exe program, a task that was previously performed by the vinterp program in the WRF SI.
