Installing WRFPLUS and WRFDA for 4D-Var Run
If you intend to run WRF 4D-Var, it is necessary to have WRFPLUS installed. WRF-
PLUS contains the adjoint and tangent linear models based on a simplified WRF model,
which includes a few simplified physics packages, such as surface drag, large scale con-
densation and precipitation, and cumulus parameterization.
To install WRFPLUS:
• Get the WRFPLUS zipped tar file from
http://www2.mmm.ucar.edu/wrf/users/wrfda/download/wrfplus.html
• Unzip and untar the WRFPLUS file, then run the configure script
> gunzip WRFPLUSV3.6_r7153.tar.gz
WRFDA
WRF-ARW V3: User’s Guide 6-9
> tar -xf WRFPLUSV3.6_r7153.tar
> cd WRFPLUSV3
> ./configure wrfplus
As with 3D-Var, “serial” means single-processor, and “dmpar” means Distributed
Memory Parallel (MPI). Be sure to select the same option for WRFPLUS as you will
use for WRFDA.
• Compile WRFPLUS
> ./compile em_real >& compile.out
> ls -ls main/*.exe
You should see the following files:
-rwxr-xr-x 1 user users 23179920 Apr 3 15:22 main/ndown.exe
-rwxr-xr-x 1 user users 22947466 Apr 3 15:22 main/nup.exe
-rwxr-xr-x 1 user users 23113961 Apr 3 15:22 main/real.exe
-rwxr-xr-x 1 user users 22991725 Apr 3 15:22 main/tc.exe
-rwxr-xr-x 1 user users 32785447 Apr 3 15:20 main/wrf.exe
Finally, set the environment variable WRFPLUS_DIR to the appropriate directory:
>setenv WRFPLUS_DIR ${your_source_code_dir}/WRFPLUSV3
To install WRFDA for the 4D-Var run:
• If you intend to use observational data in BUFR or PREPBUFR format, or if you
intend to assimilate satellite radiance data, you need to set environment variables
for BUFR, CRTM, and/or RTTOV. See the previous 3D-Var section for instruc-
tions.
>./configure 4dvar
>./compile all_wrfvar >& compile.out
>ls -ls var/build/*.exe var/obsproc/*.exe
You should see the same 44 executables as are listed in the above 3D-Var section,
including da_wrfvar.exe |
