Spaces are ok here. | Spaces are ok here. Next it will ask if you wish to CLONE an experiment. If yes, you can point this to another experiment and the setup script will try and duplicate all the RC, etc. files. For now, though, choose NO to create a new experiment. | ||
Do you wish to CLONE an old experiment? (Default: NO or FALSE) | Do you wish to CLONE an old experiment? (Default: NO or FALSE) | ||

Enter the Atmospheric Horizontal Resolution code: | <nowiki>Enter the Atmospheric Horizontal Resolution code: | ||

c48 -- 2 deg | |||
c90 -- 1 deg | |||
c180 -- 1/2 deg (56-km) | |||
c360 -- 1/4 deg (28-km) | |||

For your first time out you will probably want to enter <code>c48</code> (corresponding to ~2 degree resolution with the cubed sphere). | For your first time out you will probably want to enter <code>c48</code> (corresponding to ~2 degree resolution with the cubed sphere). | ||
Next it will ask you about the vertical resolution: | |||
Enter the Atmospheric Model Vertical Resolution: LM (Default: 72) | Enter the Atmospheric Model Vertical Resolution: LM (Default: 72) | ||
The next question is about using IOSERVER: | |||
Do you wish to IOSERVER? (Default: NO or FALSE) | |||
The "default" answer to this will change depending on the resolution you choose. For now, just accept the default. | |||
Next is a question that asks what processor you wish to run on. For example, on discover at NCCS: | |||
Enter the Processor Type you wish to run on: | |||
hasw (Haswell) (default) | |||
sky (Skylake) | |||
NOTE: At present you need access to special queues to use the Skylake, so choosing Haswell is usually a better option. | |||
After this are questions involving the ocean model: | |||

Then Land model: | |||
Enter the choice of Land Surface Boundary Conditions using: 1 (Default: Icarus), 2 (Latest Icarus-NL) | |||
Then the aerosols: | |||
Do you wish to run GOCART with Actual or Climatological Aerosols? (Enter: A (Default) or C) | |||

The post-processing script will generate the archiving and plotting scripts as it runs. The setup script that you ran also creates an experiment home directory (''HOMDIR'') as either in <code>~''USERID''/geos5/''EXPID''</code> (if you accepted the default) or in <code>/discover/nobackup/''USERID''/''EXPID''</code> (if you followed the above advice) containing the run scripts and GEOS resource (<code>.rc</code>) files. | The post-processing script will generate the archiving and plotting scripts as it runs.
