Agenda:

  1. Admin: Volunteer for taking today’s meeting minutes to post here on the Forum.

  2. Brief update from WG co-chairs and ACCESS-NRI: Yi Huang, Charmaine Franklin, Matt Woodhouse, Heidi Nettelbeck (5mins)

  3. Data update Kelsey Druken (5 mins)
    Kelsey from ACCESS-NRI will provide a brief update on support for data sharing and/or publication options available as well as propose some storage management best practice advice for the WG gdata project area.

  4. CMIP7 model plans and timelines (10+5mins) Rachel Law

  5. ACCESS-AM3

    • Update on AM3 development and how to evaluate it: Martin Dix (10+2mins)
      Martin will give a brief update on ACCESS-AM3 development and progress towards a release. A community CM3 evaluation and development process has recently started under the ESM working group. Within this access-cm3-paper-1 repo are useful scripts, e.g., SAM_jet_metrics script to investigate winds for
      higher res simulations, including location and intensity of max U850.
      Would this framework be useful for AM3 evaluation?

    • Call for AM3 alpha testers: Lachlan Whyborn (2mins)
      How to get involved with the alpha testing of the AM3 configuration.

    • AM3 aerosols and the Southern Ocean: Matt Woodhouse and Sonya Fiddes (5mins)
      Matt and Sonya will be applying learning from AM2 aerosol experiments to AM3

  6. ESA CCI SST and sea-ice dataset Heidi Nettelbeck (5mins)
    Global SST-forced experiments with ACCESS-AM3 (N512), W21C would need to follow the HighResMIP2 conventions and use the ESA CCI SST & sea-ice dataset. This dataset is the same resolution as the OSTIA one at 0.05 degrees, but provides a consistent stable record over the satellite era.

  7. Compute/storage resources: Heidi Nettelbeck (5mins)
    Any experiment proposals for Q4/2025 (875 kSU allocation)?
    → See here for how to apply for Atmosphere WG Resources.

  8. Next Atmosphere WG meeting: Feb 2026
