Namelists

There are several ways in which the model can be modified using namelist settings. This is what we cover in this chapter:

• The section Overview describes the steps to modify the namelists and provides a visual representation of the directories and files that need to be modified.

• The section Documentation explains how to find information about the namelist variables on the CESM webpage.

• The section Customizing output describes how to customize the output history files, such as changing the output frequency or adding variables to a file.

• The sections Exercise 1 and Exercise 2 offer opportunities to practice the concepts learned in this chapter.
