How to modify the calculated time step of the model

[qian yang]

dear all
To improve the efficiency of model operation,I want to modify the calculated time step of the model. But I do not know where to modify it. Can anyone help me?

You can change ATM_NCPL in env_run.xml. The default is 48 which translates to 1/2 hour time steps. For example, to run at 1 hour time steps:

./xmlchange ATM_NCPL=24
