WRF User Support and Information

Overall support to users for the WRF system is handled by the Mesoscale and Microscale Meteorology (MMM) Laboratory 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 Laboratory, 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 3.7, issued in April 2015. V3.7 contains new features, improvements to existing capabilities, and bugfixes. Information on it may be found here: WRF V3.7 Release Information.

The next major release will be targeted for Spring 2016. Information on it may be found here: WRF Release Information.

Information for Contributors: Code Submittal Requirements

Those seeking to contribute code to the WRF system must follow the procedures and meet the requirements. These include adhering to coding standards, performing code testing prior to a submit request, and supplying information and documentation for a commit. For the requirements, prospective contributors should read the document: Information for WRF Code Contributors. They should also be familiar with the policies and procedures of WRF repository and WRF release administration, summarized below and described here: WRF Code Repository and Release Administration.

Information for Contributors: Code Testing and Documentation

Code Testing— As described in Information for WRF Code Contributors: Code Testing, 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 Materials

Documentation— Code submittal requires completing a form with information on the proposed commit: a description of the commit, its purposes, and the code it affects. This is to allow the Developers' Committee to understand its structure, function, and behavior; to provide information for the repository; and to document for users the code's background.

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 management of the WRF repository and oversight of source code modification and testing. It also includes managing and overseeing the WRF release process. To guide these activities and document them for the WRF community, 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. To contact these committees, users may write to wrfhelp@ucar.edu .
