WRF Preprocessing System (WPS); Numerous physics packages contributed by WRF partners and the research community; Unified Post Processor (UPP) software package and sample scripts for several graphical packages. Other components of the WRF system will be supported for community use in the future, depending on interest and available resources. The Community Unified Post Processor requires the same Fortran and C compilers used to build the WRF model. In addition, the netCDF library, the JasPer library, the PNG library, Zlib, and the WRF I/O API libraries, which are included in the WRF model tar file, are also required. UPP uses WRF I/O libraries for data processing of all models.

You could complete the following set of instructions to run WRF on any case study, using a wide variety of initial and lateral boundary condition data sets; I’ve added some links to data sources on the MEA 716 web page.

Introduction
The WRF Preprocessing System (WPS) software was introduced in WRF V2.2.1, to replace the existing WRF SI. The static fields and grid domains are specified in the first program, geogrid. The external analysis and forecast data are decoded from the Grib format with the ungrib program in WPS. The final program in the WPS suite is the metgrid program, which horizontally interpolates the data from ungrib. The vertical interpolation has been moved to the real program under WRF.
Details on the WRF Preprocessing System (WPS) can be found in Chapter 3 of the WRF-NMM User's Guide.

WRF Domain Wizard GUI (Developed by NOAA/ESRL/GSD)
WRF Domain Wizard is a java-based graphical interface (GUI) for WPS, the successor to the WRFSI GUI. It enables users to define model domains by graphically selecting a region on an image of the Earth and choosing a map projection. The user can also define nests using the nests editor and execute the WPS programs (geogrid, ungrib, and metgrid) from within the GUI.
WRF Domain Wizard is run using Java Web Start. Java Web Start is an application-deployment technology that automatically downloads your software then launches (runs) the application.
See the WRF Domain Wizard home page to download the software and view documentation.

Welcome
Welcome to the users home page for the Nonhydrostatic Mesoscale Model (NMM) core of the Weather Research and Forecasting (WRF) system. WRF-NMM was developed by the National Oceanic and Atmospheric Administration (NOAA)National Centers for Environmental Prediction (NCEP).
Description
The current release is Version 3. WRF-NMM is designed to be a flexible, state-of-the-art atmospheric simulation system that is portable and efficient on available parallel computing platforms. WRF-NMM is suitable for use in a broad range of applications across scales ranging from meters to thousands of kilometers, including:
- Real-time NWP
- Forecast research
- Parameterization research
- Coupled-model applications
- Teaching
The NOAA/NCEP and the Developmental Testbed Center (DTC) are currently maintaining and supporting the WRF-NMM portion of the overall WRF code (Version 3) that includes:
- Nonhydrostatic Mesoscale Model (NMM) dynamic solver, including one-way and two-way static nesting;
- WRF Preprocessing System (WPS);
- Numerous physics packages contributed by WRF partners and the research community;
- Unified Post Processor (UPP) software package and sample scripts for several graphical packages.
Other components of the WRF system will be supported for community use in the future, depending on interest and available resources.
