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.
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
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
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
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:
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,
Repository and Release Administration describes
the policies and procedures.
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 firstname.lastname@example.org .
