WRF Release Information
The next major WRF release, WRF Version 3.5, will be in Spring 2013.
Developers seeking to have their codes for new capabilities for
the next major release considered by the WRF Developers' Committee
and added to the WRF repository must review
Information for Code Contributors.
Contributors may also write to email@example.com for information and for contacting
the Developers' Committee, which oversees code contributions to the WRF system
and manages the WRF repository. The Developers' Committee is described in
WRF Code Repository and Release Administration.
Candidate Features— WRF Version V3.5
A partial list of potential WRF V3.5 features is shown below.
However, ultimate inclusion of any code or features is dependent on the code's
following preparation requirements, meeting the deadline for submission,
and passing all tests.
Developers may submit code for consideration for the
release as long as the timeline and the procedures for
contribution (see Information
for Code Contributors) are followed. Developers and contributors may contact
firstname.lastname@example.org for information on providing their
code to a member of the Developers' Committee and
on preparing and testing their code prior to submission.
- Software framework improvements (e.g: ESMF V5
- New/improved physics, including: Morrison-Gettleman
microphysics, GRIMS shallow convection, climatological ozone/aersol input
for the RRTMG radiation, new modules for sea/glacial ice for
use with Noah MP LSM
- WRFDA: New instrument observations (e.g: NPP,
- WPS: Global MODIS-based vegetation dataset,
NUDAPT 250-m urban landuse dataset
- WRF-Chem: CAM chemistry, lightning parametization,
lightning NOx production
- WRF-Hydro hydrology package
- HWRF: Idealized hurricane option
