WRF User Support and Information

Overall support to users for the WRF system is handled by the Mesoscale and Microscale Meteorology (MMM) Division of NCAR, and the main page for information on the WRF Model and user support is: WRF Users' Page. The WRF system contains two dynamical solvers, referred to as the ARW (Advanced Research WRF) core and the NMM (Nonhydrostatic Mesoscale Model) core. The ARW has been largely developed and maintained by the MMM Division of NCAR, and its users' page is: WRF-ARW Users' Page. The NMM core was developed by the National Centers for Environmental Prediction, and its user support is provided by the Developmental Testbed Center. Its users' page is: WRF-NMM Users' Page.

WRF Releases

The most recent WRF release is WRF Version 3.6.1, issued in August 2014. V3.6.1 contains bugfixes and and enhancements of the prior major release V3.6 (April 2014), and information on V3.6.1 may be found here: WRF V3.6.1 Release Information.

The next major release will be WRF V3.7 and is targeted for Spring 2015. Information on it may be found here: WRF V3.7 Release Information.

Information for Code Contributors: Code Submittal and Documentation

There are coding practices and code submittal procedures for those seeking to contribute to the WRF system. These include coding standards, code testing requirements, and submittal procedures. Prospective contributors should familiarize themselves with these requirements by consulting the contributor information document: Information for WRF Code Contributors. They should also note the policies and procedures of WRF repository and WRF release administration, summarized below and described here: WRF Code Repository and Release Administration.

Among the practices and procedures for code submittal is the documentation requirement. Contributors should provide documentation on their codes so that: (i) users can understand what the purposes and background of the code are, and (ii) those supporting the WRF system to the user community can understand its structure, function, and behavior.

Information for Contributors: Code Testing

As described in Information for WRF Code Contributors: Code Testing, developers and prospective contributors of code to WRF must do preliminary testing of their codes. This consists of software testing and case testing, and the materials and information on this may be found here: Testing Data/Materials

WRF Repository and Release Administration

NCAR is responsible for the support of WRF code to the user community and for the administration of the WRF repository and of WRF releases. This includes oversight of the processes for source code modification, source code testing, and repository upkeep. It also includes managing and overseeing the WRF release process. To guide these activities and to inform the WRF community, the document WRF Code Repository and Release Administration describes the policies and procedures.

WRF repository management is handled by the Developers' Committee, and WRF release management is handled by the Release Committee. The Developers' Committee oversees additions to, and maintenance of, the repository, while the Release Committee oversees the release process. For information on contacting these committees, users may write to wrfhelp@ucar.edu .
