Get pre-compiled code

To save time and avoid unnecessary errors, we recommend using the provided pre-compiled code to run the exercises.
If you are interested in compiling the code yourself, you can do that as a separate exercise.

The pre-compiled WRFDA code can be accessed from /classroom/wrfhelp/PRE_COMPILED/WRFDA.

You should copy the pre-compiled code into your local working directory. Follow the steps below:

mkdir /classroom/users/${USER}/DA    (your main working directory)
cd /classroom/users/${USER}/DA
cp /classroom/wrfhelp/PRE_COMPILED/WRFDA/WRFDA_compiled.tar.gz .
tar -xzf WRFDA_compiled.tar.gz

This will generate the WRFDA directory containing the compiled WRFDA code. This WRFDA package is pre-compiled to run in parallel (dmpar) mode using the GNU compiler (gfortran/gcc 5.2.0). It was compiled with the 4DVAR capability, and so can be run for both 3DVAR and 4DVAR exercises

The pre-compiled WRFPLUS package can be accessed from the same directory. It is not necessary to copy over the WRFPLUS code unless you will be running it directly, like with the FSO exercise.

cd /classroom/users/${USER}/DA
cp /classroom/wrfhelp/PRE_COMPILED/WRFDA/WRFPLUSV3_compiled.tar.gz .
tar -xzf WRFPLUSV3_compiled.tar.gz
