Weather Research & Forecasting

Weather Research and Forecasting Model (WRF) is a state-of-the-art atmospheric modeling system designed for both meteorological research and numerical weather prediction. It offers a host of options for atmospheric processes and can run on a variety of computing platforms. WRF excels in a broad range of applications across scales ranging from tens of meters to thousands of kilometers, including the following.

• Meteorological studies

• Real-time NWP

• Idealized simulations

• Data assimilation

• Earth system model coupling

• Model training and educational support

The Mesoscale and Microscale Meteorology Laboratory (MMM) of NCAR supports the WRF system to the user community, and maintains the WRF code on GitHub. MMM provides user assistance via an online Support Forum. MMM also issues WRF releases, conducts WRF tutorials, and hosts the annual WRF and MPAS Users' Workshop.

The WRF system is available via free download through these pages. In addition to providing the code and documentation for WRF system, this site provides information and links on WRF code contributions, releases, and events.
