The original development of the WRF system was a joint, long-term effort by a collaboration of organizations (see home). The coordination of the project was shared, involving the partner institutions and outside advisory positions. This page summarizes WRF's historical and active administrative components. As at this point the core development of WRF has been accomplished and the system is mature, most of the original entities are no longer active. The one board that does remain active, however, is the Research Applications Board (RAB). In addition, the WRF Developers' Committee and the WRF Release Committee have taken over the duties of oversight of code contributions, repository maintenance, and the issuance of new model releases. The active and historical administrative entities are described below.

WRF Developers' Committee and Release Committee

Currently, WRF repository and release management is handled by two committees: the Developers’ Committee and the Release Committee.  The Developers’ Committee oversees additions to, and maintenance of, the code repository, while the Release Committee oversees the new releases to the user community.

The Developers’ Committee has responsibility for maintaining the WRF system software by implementing procedures for, and overseeing the process of, code contributions, code testing, and repository upkeep. It determines whether code modifications are acceptable for inclusion, and it manages the repository. The Release Committee oversees the preparation and issuance of WRF major releases.  It also provides release information to the user community.  Both of these commmittees meet regularly, and the document WRF Code Repository and Release Administration describes the groups and their functions in full.

WRF Research Applications Board

The primary function of the WRF Research Applications Board (WRAB) is to review trends, emerging science, and new technologies and to identify and prioritize those elements with the greatest opportunity for advancing the capabilities of WRF for research community use. The board meets annually at the WRF Users' Workshop. The head of the WRAB is a senior scientist recognized for leadership in mesoscale numerical weather prediction research, and membership includes leaders of WRF working groups and of the research community. WRAB members are selected for their research expertise and span a cross-section of the atmospheric sciences community to provide the vision and leadership for sustaining WRF as a modeling system for research. The WRAB may be contacted at wrf-wrab@wrf-model.org.

WRF Executive Oversight Board

During WRF's formative years and initial developmental phase, the WRF Executive Oversight Board (WRF ExOB) was the top level of WRF program management and operated in accordance with the WRF Agreement in Principle (AIP), the agreement of the partner institutions. The AIP signatory organizations each designated one senior-level voting member to the board. The ExOB focussed on the overall progress of the effort and on budgetary issues. It appointed a Program Coordinator, as well as the members and chairmen of the WRF Research Applications Board and WRF Operational Requirements Board.

WRF Operations Requirements Board

The primary function of the WRF Operational Research Board (WORB) was to define WRF program requirements necessary for the system to support operational and real-time forecasting applications. Requirements were those scientific and technical attributes needed for WRF to be a powerful tool for the operational and real-time communities. The WORB was to review WRF coding and documentation standards developed by the WRF working groups and, in concert with the Developmental Testbed Center (DTC) and Operations Testbed Centers, ensure their suitability for sustaining WRF for operations as well as research. The head of the WORB was an ex officio member of the WRAB.

WRF Development Teams and Working Groups

In the initial development of the WRF system five development teams were set up: Numerics and Software, Data Assimilation, Analysis and Verification, Community Involvement, and Operational Implementation. Each team coordinated efforts from subsidiary working groups within its area, and the original teams and working groups (WG) are listed below. While the teams are no longer active, a number of the working groups still communicate and meet at the WRF Users' Workshop. For information on active working groups, one may contact wrfhelp at wrfhelp@ucar.edu.
