Changing EAMxx output is still kind of a hack. From your case directory, edit run/data/scream_default_output.yaml . You can add any variable stored in the field manager or added as a special diagnostic. You can get a list of available variables by printing out the DAG for your run. To do so, issue ./atmchange Atmosphereatmosphere_DAGdag_Verbosityverbosity_Levellevel=4 (as noted in Step 6). Available verbosity levels are: <=0 produces no DAG, 1 only prints the atm processes DAG, 2 adds fields names to the dag nodes, 3 adds fields layout info, and 4 also adds grid name where the field is defined. The DAG file will be named scream_atm_dag.dot. Word does a nice job of viewing these files.

./xmlchange ATM_NCPL . Note that this is the number of atm timesteps per day so the model timestep (commonly known as dtime) is 86400 sec/ATM_NCPL. See the dycore settings link at the end of this section for guidance on choosing dtime.
