Participants: 15

Chair: @eunpalim

1. Opening and Welcome:

  • There are no speakers confirmed for future meetings. Please consider presenting, or inviting a colleague to present. Members are encouraged to reach out to any co-chair or @spencerwong if they are interested in presenting.
  • Future scientific presentations do not need to be fully polished; works in progress or discussion-based topics are welcome.
  • Add any items they want to discuss to the working group agenda via the topic on the forum.

2. Summer meeting schedule:

  • Discussion was held on when to have the final meeting of the year. We will plan to have a regular science presentation on 21/11 and a CMIP7 fast track update on 5/11, and then have a break in meetings until February.

3. Shared experiments/ACCESS-NRI resources

  • ESM project lg87 has used ~435 KSU of its 875 KSU allocation for this quarter. /g/data storage steady at 35TB. Most of the compute allocation for this quarter has been allocated for experiments, however there may be a small amount currently unallocated.
  • The holiday period and beginning of the year typically have low compute usage. If you have ideas for experiments, it’s a good time to put forward any proposals. See guidelines for how to do this. There are often used resources we can access if there are projects to use them.
  • Guidelines around lg87 gdata storage usage were discussed. There currently is no policy, however ideas including 6 month storage limits, and a central spreadsheet for tracking experiments were proposed. The experiment proposal template will be updated to include sections on required storage time, and plans for the data once it’s removed.
  • ACCESS NRI is working on guidelines for WG shared resources which will address some of these issues.
  1. CMIP7 Fast Track update:
  • @RachelLaw presented updates on the development of ACCESS ESM 1.6 for the CMIP7 fast track.
  • Current work includes @pearseb’s updates to WOMBAT light using generic tracers, replacing CABLE 2.4 with CABLE3, testing convective momentum transport in the UM, swapping the sea ice component to CICE5, and making the MOM5 configuration better match OM2.
  • @arnoldsu and @RachelLaw shared results from testing convective momentum transport (CMT) in the UM, and from updating the land component to CABLE3.
  • @tiloz provided an update on on the recent forcings workshop, noting that forcing datasets for CMIP7 are starting to be made available, and noted the need for sustainable funding for this work.
  1. Orbital Parameters for ESM 1.5:
  • @spencerwong demonstrated how to set custom orbital parameters in ESM 1.5 using a new pre-release version of the executables. A tutorial on using the prerelease is available here.
  • An upcoming release of ESM1.5 will include these changes along with other updates.
