The subdirectories in this directory contain Python scripts to run various "experiments" using Glimmer/CISM. Some details about the experiments and how to run them are given in the README.md files found in each subdirectory and they are summarized in the documentation.

This directory also contains two Python source files:

netCDF.py

netCDF.py is a "module" (that is, code that is meant to be used by other Python programs, not run by itself) that allows the Python scripts in the subdirectories to use whichever of the three python netCDF file packages, Scientific.IO.NetCDF, netCDF4, or pycdf, that the user has installed. There are links to this module in each of the subdirectories, but is is also included in this directory for reference.

Of the three python netCDF file packages, pycdf is NOT recommended. There have been problems with some versions of this module on some computers. If you run netCDF.py by entering the following on a command line

python netCDF.py

a line should be output telling you which netCDF package will be used when
running the Glimmer/CISM scripts on your computer.

viewNetCDF.py

viewNetCDF.py is a script for viewing the netCDF files that are read and/or written by Glimmer/CISM. There are other tools available for doing this, such as ncview; You may (or may not) prefer viewNetCDF.py; it works better on some systems than others. To run viewNetCDF.py enter the following on a command line:

python viewNetCDF.py filename.nc

where filename.nc is the name of the netCDF file that you want to view. Left click on a variable name that appears in the list at the top left of the Graphical User Interface (GUI) that appears, then left click on the "plot" button. In addition to the options displayed on the GUI there are some options "hidden" in a pop-up menu that appears if you right click on the GUI.
