test_set_interior: process to create initial condition files / baselines should be kept in repository

[mnlevy1981]

There are some scripts in mnlevy1981/MARBL-notebooks that are used to generate the initial condition files that should be streamlined and moved to this repository instead. Also, need to have a README file outlining the process:

1. Create a G1850ECO case using T62_g17 resolution

2. XML changes:

   • DOUT_S = FALSE
   • STOP_N=1 (and keep STOP_OPTION=ndays)
   • POP_TAVG_R8=TRUE

3. user_nl_pop needs the following

   lecosys_tavg_all = .true.
   time_mix_opt = 'avgfit'
   surf_avg_dic_const = 0
   surf_avg_alk_const = 0
   

4. user_nl_MARBL needs the following

   lecovars_full_depth_tavg = .true.
   

5. SourceMods

   • Update ocn.base.tavg.csh to get nstep output in the first stream (and write new files for each step)
   • Update ecosys_diagnostics to remove all the FvPER and FvICE variables (POP doesn't define them when surf_avg = 0 in the namelist)
