To download the Medium-Range Weather Application, with externals pointing to its constituent components, go to your $HOME directory and enter:
git clone https://github.com/ufs-community/ufs-mrweather-app.git -b ufs-v1.1.0 $HOME/UFS_training/my_ufs_sandbox
Then, to get the components
./manage_externals/checkout_externals
This will clone the ufs-v1.1.0 branch of the ufs-mrweather-app repository and check out all of the externals and sub-modules. The process will take several minutes and show the following progress information in the screen:
Checking status of externals: model, fv3gfs_interface, cime, emc_post, nems_interface,
Checking out externals: model, fv3gfs_interface, emc_post, cime, nems_interface,
The repositories URL, tag number and their location path of external and sub-modules are defined in the text file Externals.cfg. Users can check this file and match the new cloned repositories with their local paths.
Once the externals have been been downloaded, you can proceed to the next step, setting up the environment.
