What version of the code are you using?
CESM2.1.5
Have you made any changes to files in the source tree?
I am producing additional spectral radiation diagnostics with COSP-RTTOV. I am also producing additional output from RRTMG and cam_diagnostics.F90. However, I do not believe these source mods are related to this thread.
Describe every step you took leading up to the problem:
I am trying to produce restart files for 07-2024 in FHIST simulations.
1. Created a case that branches from a previous AMIP simulation. I have created my own SST/sea ice boundary conditions 2015 - onward.
2. Ran from 2015 through 06-2024 in 12 month increments using CONTINUE_RUN=TRUE. The last increment is 6 months from 01-2024 through 06-2024. The restart files in the run directory all have the timestamp "2024-07-01-00000" except for the "cam.i." file, which is timestamped at the beginning of the restart "cam.i.2024-01-01-00000". I believe that this is the cause of the error and is likely due to branching in the middle of a year rather than in January.
3. Created a new FHIST case to branch from this run and produce additional output fields beginning 07-2024. The RUN_REFDIR for this case points to the restart files from the previous run as in previous branched runs. But it cannot point to the "cam.i." because it does not share the same timestamp.
4. Submitted the new case, which fails when it is unable to open a "cam.i." file with the correct timestamp.
GETFIL: FAILED to get 20251107_103024.FHIST.f09_f09_mg17.cesm2.1.5_port_ERA5branch.cam.i.2024-07-01-00000.nc
The two cases that I am working with are here:
Run to produce restart files: /glade/u/home/jonahshaw/Cases/CESM2/cesm2.1.5_rttov/20251107_103024.FHIST.f09_f09_mg17.cesm2.1.5_port_ERA5branch
Future branching run: /glade/u/home/jonahshaw/Cases/CESM2/cesm2.1.5_rttov/20251114_105032.FHIST.f09_f09_mg17.cesm2.1.5_PREFIREPRIME
Describe your problem or question:
My questions are:
- Why did my branching run not produce all of the files needed for restarting? Or alternatively, can I just use the cam.i. file that it did produce when I try to branch (e.g., create a softlink connecting the "correct" timestamp with the existing "cam.i." file? When testing the first case I continued the run in increments smaller than a year multiple times, so the updated "cam.i." file must not be necessary, right?
- If I need to produce an updated "cam.i." file, how do I efficiently do that? I just want to rerun the last 6 months of my first simulation with "init_hist='ENDOFRUN'". Do I need to create an entirely new case to branch from at the beginning of the previous year where all restart files have the same timestamp?
I found this relevant thread, but it doesn't not answer my specific problem:
Cannot find restart file named ...cam.i...
Thank you!
