MOM can produce many types of diagnostics and all are described within this chapter. How to organize and view results from these diagnostics has been a major problem in the past. With the adoption of a NetCDF standard, results can now be viewed almost without effort. A good way to visualize and further analyze results is to use Ferret which is a graphical analysis tool developed by Steve Hankin (1994) at NOAA/PMEL (URL: http://ferret.wrc.noaa.gov/Ferret/ which can be reached through clicking here email: ferret@pmel.noaa.gov). This package is highly recommended because it works well with large datasets, supports non-uniform staggered grids, allows dynamic regridding of data, abstract variables, modulo axes, and contains many useful transformations and built in functions.
