WRF Users and Websites
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 WRF and user
support may be found
at www.mmm.ucar.edu/wrf/users. 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 here: 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, with its users' page here: WRF-NMM Users' Page.

These include coding standards, code testing requirements,
and submission procedures. Prospective contributors
should familiarize themselves with these
requirements by consulting the document
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.
Contributor Code Testing Information
As described in
for WRF Code Contributors,
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:
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 responsibility
for oversight of the processes for source code modification,
source code testing, and repository upkeep. It also includes
responsibility for 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.
management is handled by the
Developers' Committee, and 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 email@example.com.
