AMS 2008 Presentation
What is WPS? WRF Preprocessing System (WPS) Developed at NCAR for WRF ARW and NMM Released with WRF V2.2 and replaces the previous WRF
SI (standard initialization) WPS is Three Programs
geogrid.exe – localizes the domain defined in namelist.wps and creates a NetCDF output file. It extracts global geographical data (e.g. soil moisture, vegetation, albedo, etc.) and maps it to the domain projection.
ungrib.exe -- decodes and extracts atmospheric parameters from GRIB files in order to initialize WRF
metgrid.exe -- combines the meteorological data from ungrib with the NetCDF output from geogrid in order to produce a series of NetCDF files that are used to initialize WRF.
What is WRF Domain Wizard (WDW)?
Successor to the WRFSI GUI and is the graphical user interface for WPS Note: the older WRFSI GUI is not compatible with WPS
Standalone application or run from within WRF Portal WDW Features
Supports ARW and NMM Define the region and projection of a domain on map Define any nests Write information to namelist.wps Run the WPS programs Visualize the netCDF output files
