Determine experiment parameters

Namelist:

• You should can edit the atmospheric model namelist file fort.4. It contains Fortran namelists which control model settings and switches.
• An important switch to edit is in namelist NAMRIP the variable CSTOP. Set this to the desired length of the forecast experiment.
• Experiment i4xc can be run for up to 144 hours (6 days) by setting CSTOP='h144'.

Experiment configuration file: 

• You should can edit the exp-config.h file which determines settings for this experiment.
• The oifs-run script will read the settings from this file.
• Alternatively, the settings can be passed to the oifs-run script via command line parameters, which takes precedence over the exp-config.h settings.
