Restarting CSIRO CMIP6 historical runs

Hello everyone!

I’ve been trying to restart a historical run with no success. I want to restart it from year 1960 and apply some perturbations.

What I’ve done so far:

  1. git cloned the esm-historical configuration directory

  2. changed start year at config.yaml to 1960

  3. changed ‘inidate’ and ‘init_date’ to 19600101 in ice/input.nml

  4. changed ‘model_basis_time’ to 1960

  5. changed the following in warm_start.sh: project=p66; user=cm2704; expname=HI-14; source_year=1960 and run the warm start scripts

  6. when running the warm start script I’ve got the following warnings:
    /g/data/hh5/public/apps/miniconda3/envs/analysis3-23.04/lib/python3.9/site-packages/mule/stashmaster.py:259: UserWarning:

    warnings.warn(msg)

  7. If I try to put the model to run it crashes at the very begging with payu error code 134. This seems to be related to forcing/restart files and the same warning as above appears in the payu error log file.

Any ideas on how to make this restart work are welcome.

Thanks,
Gabriel

Hi Gabriel,

I will try to get back to you within the end of the week :slight_smile:
