WRF Var Updates 3.0.1.1 (detail)
WRF Var Update 3.0.1
The WRF-Var tar file
has been updated to Version 3.0.1 on August 4, 2008.
In this release, the following new features and updates are provided:
1) Changes to the WRF build system to allow WRF-Var to be compiled without setting the WRF_DA_CORE environment variable. Now, WRF-Var can be compiled by typing "./configure wrfda" followed by "./compile all_wrfvar", without setting WRF_DA_CORE. However, the existing procedure for building WRF-Var will still work exactly as before.
2) Unified WRF/WRF-Var namelist.
3) Update the var directory with the head of the WRF-Var developmental repository.
4) Fix several bugs.
5) Remove obsolete features (e.g. MM5/GFS-based background errors).
6) Verification package (provided only as tools, with limited documentation and caveats).
With analysis_type="VERIFY", there are two problems: a) statistics files are not written out; b) model data below lowest model levels and above highest model level are incorrectly set to zero, which leads to incorrect O minus B values (fixed in 3.0.1.1).
7) Utilization of observations packed in NCEP PREPBUFR format - beta feature, requires more testing.
8) Inclusion of various scripts and NCL based graphics (provided only as tools, but not supported)
For compile and run instructions, please refer to the updated User's Guide
