• Plan to have one just more meeting this year (Dec 7th) and no meetings in January. First meeting of 2023 will be February 1st.
• We have two volunteers for December and February (thanks @jemmajeffree and Francois Delage). Would be good to have at least one more speaker for mid February locked in before break.

Shared experiments/ACCESS-NRI resources

• ESM WG project lg87 has /g/data allocation of 50TB, same for /scratch and F&P WG transferred their compute allocation for this quarter, so there is 1.75MSU total.
• @eunpalim’s Triple La-Nina experiment: @griff and @lynzhou running this. Done 1 start date so far and used 130KSU/1TB so far. Will run 17 more.
• Any proposals for shared experiments for next quarter? See guidelines for how to do this. First meeting is in February, so not much time to organise to utilise resources.
• ACCESS-NRI Merit Allocations Guidelines: Release scheduled for today. Overview from @Aidan and discussion/questions.

Science talk

Recording Hutchinson ESMWG Nov 23

Works for Miocene, but still haven’t problems with orography. 7 orography variables in the UM restart file. Works with small changes, but trying to just change the areas where miocene changes leads to a model crash. Can’t find how this was originally generated.

Set up ACCESS-ESM1.5 for Miocene land-sea mask

This is a work-in-progress guide to setting up ACCESS-ESM1.5 for the Mid-Miocene climate optimum (15 Ma). There are several aspects that are unfinished, but posting here now as it may be useful as a starting point. The scripts referred to here in this github repository and the accompanying files will be added to lg87 on Gadi in the near future. Some of the following is a clone of the README from the github repo, but some additional steps will be added for starting the experiments. Temporary loc…

ACCESS-CM2 updates

@dhb599 ACCESS-CM2 PPE Experiments using UKCP18 PPE Settings. ENSO not good. Quasi-biennial life-cycle of ENSO. 7 out of 10 metrics are good. Only ENSO stands out as bad. Run group of 8 PPEs. Large TOA Energy imbalance: 0.4 W/m².

Chose best and ran more tests. Less than 0.2 W/m² vs 0.4.
