Exercise Overview

Exercise Overview#

Learning Goals#

In this exercise, you will gain hands-on experience modifying CESM namelists and examining the impact of those changes on a simulation.

By the end of this exercise, you will be able to:

  • Edit component-specific user_nl_* files.

  • Generate and inspect updated namelists.

  • Run a CESM simulation with custom namelist settings.

  • Verify that your namelist changes have been applied correctly.

Exercise Options#

Complete at least one of the following exercises:

  1. Output High-Frequency Data in CAM

    Modify CAM namelist settings to generate output at a higher temporal frequency and examine the resulting history files.

  2. Modify a CAM Tuning Parameter

    Change a CAM tuning parameter through the namelist, run the model, and investigate the impact of the modification on the simulation.

These exercises provide practical experience using namelists to customize CESM simulations without modifying the source code.
