## Introduction CSIRO and ACCESS-NRI have developed, configured and ran the ESM1.6 spin-up experiments for the upcoming cmip7 contribution. This thread is intended to document the exact model executables and forcings used for the esm1.6 spin-up experiments ([previous example](https://forum.access-hive.org.au/t/access-om2-control-experiments/258)). In particular, changes to the executables, bug corrections and updates can also be documented here. | | | | --- | --- | | Name: | pi\_concentrations | | Years: | 0-222 | | GitHub repo: | [GitHub - ACCESS-Community-Hub/access-esm1.6-dev-experiments at pearseb-dev-20241220-1 · GitHub](https://github.com/ACCESS-Community-Hub/access-esm1.6-dev-experiments/tree/pearseb-dev-20241220-1) | | Exe versions: | [access-esm1p6/pr27-5](https://github.com/ACCESS-NRI/ACCESS-ESM1.6/pull/27#issuecomment-2547375784) | | Inputs: | /g/data/vk83/configurations/inputs/access-esm1p5/ … /g/data/vk83/prerelease/configurations/inputs/access-esm1p6/ … | | Outputs: | /scratch/p66/pjb581/access-esm/archive/pi\_concentrations-expt-c55f7217 - (as of 10/6/2025) moved to /g/data/p73/archive/CMIP7/ACCESS-ESM1-6/development/pi\_concentrations-expt-c55f7217 | | Restarts: | /scratch/p66/pjb581/access-esm/archive/pi\_concentrations-expt-c55f7217 | | Brief description: | Spin-up run with the 1 degree ACCESS-ESM-1.6 with 650 years continuous run (as of writing) | | Simulation started: | 20th December 2024 (all run on Gadi) | | People: | Pearse Buchanan (@pearseb), ? | | Linked articles: | | | | | | --- | --- | | Years: | 222 - 272 | | Exe versions: | [access-esm1p6/pr31-1](https://github.com/ACCESS-NRI/ACCESS-ESM1.6/pull/31#issuecomment-2597151083) | | Outputs: | /scratch/p66/pjb581/access-esm/archive/pi\_concentrations-expt-c55f7217 - (as of 10/6/2025) moved to /g/data/p73/archive/CMIP7/ACCESS-ESM1-6/development/pi\_concentrations-expt-c55f7217 | | Restarts: | /scratch/p66/pjb581/access-esm/archive/pi\_concentrations-expt-c55f7217 | | Brief description: | WOMBAT-lite code updated with sinking bugfix.

In version C, test-PIspinup-Sept-C is restarted from year 402 coming from the AprilSpinUp (restart 300). The reason for starting earlier in the run is that by year 600 of AprilSpinUp (where Sept-A begins), 500 after the solar constant change, the region in the Southern Ocean has already cooled down considerably and is already spilling water into the excessively cold water of deep ocean in the rest of the model (ocean timescale to reverse this is long). This suggests we restart the model from an even earlier time. However there is a significant step change in ocean dynamics due to a revision to ocean BGC at approximately year 280(experiment counter=382). This suggests we start after this has occurred. As such the decision was made to start from restart300(experiment counter=402), 200 years earlier that Sept-A. | | Further Notes: | To clone this simulation fully intact use `payu clone ``git@github.com``:ACCESS-NRI/access-esm1.6-configs.git -B test-PIspinup-Sept-C` | | --- | --- | | People: | Ian Harman (@inh599 ), Tilo Ziehn (@tiloz), Rachel Law (@RachelLaw ), Jhan (@Jhan ), Pearse Buchanan (@pearseb) Spencer Wong (@spencerwong ), Anton Steketee (@anton), Dougie Squire (@dougiesquire ) | | | | | name | test-PIspinup-Oct-A (PBS jobname:Oct-A) | | --- | --- | | Years: | 883-present (restart280 from test-PIspinup-Sept-A) | | GitHub repo: | [GitHub - ACCESS-Community-Hub/access-esm1.6-dev-experiments at test-PIspinup-Oct-A-dev-20251014-1 · GitHub](https://github.com/ACCESS-Community-Hub/access-esm1.6-dev-experiments/tree/test-PIspinup-Oct-A-dev-20251014-1) | | Exe versions: | [access-esm1p6/2025.10.000](https://github.com/ACCESS-NRI/ACCESS-ESM1.6/releases/tag/2025.10.000) | | Outputs: | /g/data/p73/archive/CMIP7/ACCESS-ESM1-6/spinup/Oct-A | | Restarts: | /g/data/p73/archive/CMIP7/ACCESS-ESM1-6/spinup/Oct-A | | Brief description: | This is a continuation of Sept-A spinup with a new executable.
