WRF4DVAR编译问题

网络小丁丁

有没有人遇到过WRFDA_3DVAR可以编译出da_wrfvar,但是使用4dvar模式就编译不出da_wrfvar.exe这个一般是什么问题

请问楼主解决了吗？我现在也遇到了这个问题。先谢谢楼主了~~

看是不是这个问题 “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.”

4DVAR的编译就是在WRFPLUS里编译吧

编译完WRFPLUS 后再编译WRFDA

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

这部分难道是在和3DVAR一样的那个WRFDA里进行编译的，只有./confugure wrfplus 和./compile em_real是在WRFPLUSV3下进行的？非常感谢您

我已编译过3DVAR了，会影响4DVAR吗？它俩应该是两个不同的目录对吗

不影响  可以同时存在

石破天惊

影响的，4DVAR的da_wrfvar.exe会把3DVAR的覆盖掉
