Note: In the following, we assume the user's shell is bash. If it is instead csh or tcsh, the commands used below for setting variables must be modified by prepending the string "set " to each. For example, to set a variable named my_var to the value "hello", in bash we use
my_var="hello"
while in csh/tcsh, we use
set my_var="hello"

For convenience, set some environment variables to more easily navigate in your work space on Cheyenne. In this tutorial, we will use /glade/scratch:

SCRATCH_DIR=/glade/scratch/$USER

SR_WX_APP_TOP_DIR=$SCRATCH_DIR/ufs-srweather-app

where $USER is your login/username, and $SR_WX_APP_TOP_DIR is the path in which you will clone the GitHub repository in the next step. Go to your work space on Cheyenne:

cd $SCRATCH_DIR
