In order to compile and run the UWCOMMAS model, you must have crm_clean.tar in your home directory. Once you have this file, follow the steps below to untar, compile, and run the UWCOMMAS model.

1) To untar and unzip the UWCOMMAS file, use the basic commands: " tar xzf crm_clean.tar.gz "
2) open "Makefile" with any text editor, preferably in Unix to avoid hidden characters.
3) Change TYPE, TRACER, and ADVECTION_METHOD, if needed. After this, save the file and close it.
4) Type "make clean" to remove unnecessary files, then type "make all" to compile the program.

INITIALIZATION

6) Run "init"
7) Move the output file to rename it "fort.12"
8) Next we need to tell UWCOMMAS how we want the model to run (i.e. start time, time steps, etc.)

WE ARE READY TO RUN!

A) Type in the following command: ./drive > drive.log 2>&1 &
B) Your file output will be default to .cdf file allowing you to use them in MATLAB/IDL or other .cdf programs.

GOOD LUCK!
