cd WRFV3

Inside this directory, you will find a number of files and directories.
Below are descriptions of some of the files and directories to take special note of. 

- The 'README' files contain useful information about the code and how to set up and run the model.


- Source code directories:
       dyn_em/      Directory for ARW dynamics and numerics
       dyn_nmm/     Directory for NMM dynamics and numerics, supported by DTC.
       dyn_exp/     Directory for a 'toy' dynamic core
       external/    Directory containing external packages, such as those for IO, time keeping, and MPI
       frame/       Directory containing modules for the WRF framework
