Subject: WRFVAR release for 2005 KMA project
Dear Mi-Seon
I'm pleased to say we've successfully completed our global testing
of
the WRFVAR code, which we are now making available on our web
site.
This, combined with the OBSPROC software which Yong-Run will be
sending
separately is the final deliverable of the KMA 2005 Project.
It combines the radiance, alpha control variable and KMA BUFR
convertor
codes into a single version. You already have this code in
separate
releases from us, but this combined version has integrated the
three,
and as well as resolving a few bugs has a range of new features:
* Background error creation gen_be stage0 has been completely
re-written. Details in da_3dvar/doc/gen_be/gen_be.doc. We
recommend you
convert to it.
* The RTTOV library is picked up externally, in a similar way to
NETCDF.
Define environment variable RTTOV to point to the directory with
your
RTTOV code before running configure
* Software engineering improvements to bring WRFVAR more in line
with
WRF
* Can now be compiled with g95 compiler on Linux and Mac
* Your kma2netcdf changes incorporated (but not the convertor or
RADAR
changes)
* New scripts to run the entire WRF system, SI, real, WRF, WRFVAR,
OBSPROC, WRF_BC for extended trial periods. See tools/run_wrf
* New script to run WRFVAR defining namelist input from
environment
variables. See run/DA_Run_WRF-Var.bsh
As part of our efforts to improve code maintainability, as agreed
we
have removed the following features:
* QN minimisation option
* CV options 1-3. Background errors are now either global (old
CV_options=4) and regional (old CV_options=5)
Please note this is a release for global use, consistent with the
focus
of the 2005 project. We have begun testing with your new regional
case,
and will report back on issues that arise. In particular we do not
have
a KMA test case including Radar for regional background errors
(CV=5)
The wrfvar file can be downloaded from

If you encounter any problems, please don't hesitate to contact me.
Best Wishes
John Bray
