WRF Model Users' Page
Welcome to the users' page for the Weather Research and Forecasting Model (here referred to as "WRF", for short). WRF is a state-of-the-art atmospheric modeling system that is applicable for both meteorological research and numerical weather prediction. It offers a host of options for atmospheric physical processes and can run on a variety of computing platforms. WRF is suitable for a broad range of applications across scales ranging from tens of meters to the global, including the following:
- Meteorological investigations
- Real-time NWP
- Idealized atmospheric simulations
- Data assimilation studies and development
- Coupling with other earth system models
- Modeling and model use instruction and training
The Mesoscale and Microscale Meteorology (MMM) Division of NCAR supports the WRF system to the user community and maintains the WRF code. MMM supports the wrfhelp service, which provides user assistance and delivers WRF news. MMM also issues WRF releases and hosts the annual WRF Users' Workshop.
The WRF system is available via free download through these pages. In addition to providing the code and documentation for the core WRF system, this site provides information or links on WRF use, releases, known problems, events, and code contributions. WRF-related systems and capabilities with additional pages are listed below:
- WRF Data Assimilation System (WRFDA)
- WRF Atmospheric Chemistry Model (WRF-Chem)
- WRF Hydrological Modeling System (WRF-Hydro)
The 16th Annual WRF Users' Workshop will be held June 15 - 19, 2015, in Boulder, CO. Registration is now open. Click here to register, and for additional information.
The WRF User's Summer Tutorial will be held July 27 - Aug 7, in Boulder, CO. It will include Basic WRF, WRF-Chem, and WRFDA. Registration is now open. Click here to register, and for more information.
