Warm starts in ACCESS-ESM1.5

Hi everyone,

I am currently attempting to use the latest release of the ACCESS-ESM1.5 model to perform a series of freshwater perturbation experiments using the run ACCESS-ESM1.5 instructions. I am trying to branch off the preindustrial control at different years using the updated warm-start.sh and other files found here, previously discussed in this post, which have been adapted from the previous release.

However, even though warm-start.sh is building the expected /restart000 directory, the runs still fail. I am currently using the PI-02 restart files in/g/data/p73/archive/CMIP6/ACCESS-ESM1-5/PI-02/restart/ but would ultimately like to use the restart files from PI-01, but I suspect that will require modification of warm-start-csiro.sh.

I am new to using ACCESS-ESM1.5 and unsure if there is a simple step that I am overlooking.

Thanks in advance for any help!

Hi Patrick

Can you please share the error you are getting ?

Also - can you please push your configuration to your github fork of the esm1.5-configs repository, I will have a look.

If you aren’t familiar with git / github, here are some useful instructions

A once-off setting it github commandline client
the actual uploading of a config

Hi Anton,

Thanks for your reply, and the git instructions.

The error I’m getting is
FileNotFoundError: CICE restart file not found in /scratch/lo70/pb8549/access-esm/archive/PI-02-byear-701-test2-PI-02-byear-700-test2-665d49cc/restart000/ice. Expected iced.07000101 to exist. Is 'dumpfreq' set in cice_in.nml consistently with the run-length? error.

I have pushed my template config to github here, as well as the failed run, the error file can be found here here.

I suspect this issue is that in archive/restart000/ice the warm start files built iced.7000101 but the model is looking for iced.07000101.

Thanks again!
Pat

Nice one

I think you’ll be fine to rename iced.7000101 to iced.07000101 in your restart dir.

If you are starting a new experiments, it’s neater to specify the initial restart files in restart: line of config.yaml here, instead of linking to an archive directory.

Sorry I am not very familiar with the warm start scripts, so I may have missed something.

Hi @Pat, just a quick update on the warm-start scripts. It looks like scripts were incorrectly omitting the leading zero when renaming the ice restart files. I’ve updated the scripts here to fix this up, and so they should avoid this error in the future.
