Some more resources (that I may or may not have posted on other threads!)
NASA GEEBITT: A simple Excel Energy Balance model
Free Data Analysis software (use these if you are trying to find a way to visualize model output from large data files. Most run on Mac and PC, and possibly Linux):
Integrated Data Viewer (distributed by Unidata) - Allows you to look at data files in various formats.
Panoply NetCDF data viewer - great for looking at model results that are typically in netCDF format.
FERRET - Data visualization software for looking at large gridded data sets.
