ESM working group: Meeting notes 2023 (Archived)

Date: 27/04/2023

Participants: 20

Working group goals:

  • Platform for Australian researchers to have input in versions and configs used by community for research
  • Currently based on configurations of ACCESS-CM2 and ACCESS-ESM1.5
  • Also based on applications and research done with models. From paleo to future projections.
  • Build a community on research.
  • Co-develop future versions.
  • Set up new collaborations and strengthen existing collaborations across projects and organisations.
  • Allocate ACCESS-NRI compute (1.25 MSU per quarter) and some storage for shared work/goals

Ran through introductions of participants, who they were and their research interests.

Q: What is role in ESM Working group in coupled model develeopment? Working group can set priorities and work on some configurations and pass back to ACCESS-NRI.

Q: Who is responsible for coupled model development work in ACCESS-NRI if there is no coupled model group? Good question, and something that is being worked through. Will involve collaboration between modelling groups and be governed by priorities of model release.

Move to CMIP7, group can be important to prioritise which models to continue to support, and where development needs to go.

Keep ESM1.5 or need a faster new model? Dietmar flagged requirement for 100 model years/day. Also currently working on UM with N48 atmosphere. Paleo needs to model carbon cycle. If possible dynamic land surface. Don’t care so much about atmospheric resolution.

Future of marine carbon cycle?

CM2 and ESM1.5 both have their uses.Need multiple configurations. Not just one model. WG can be a forum to discuss what configurations are required.

@wghuneke working with @MartinDix on CM version with 0.1 deg ocean, but obviously slower, and still ironing out some errors with the 0.25 deg ocean CM version.

Map out intersection points of interest. e.g. land/sea masks and ancillaries. Has been challenging, pool resource and improve processes.

Land-sea masks key step for changing coupled model configurations. Knowledge is limited to a few people. Can ACCESS-NRI form a team to do this work. Create package to do this usable by community.

Re: meeting frequency: Monthly maybe too far apart. If one is cancelled the gap is too big.

Have a focus on each meeting, allows those who are keen to try and make it. Also good to keep it diverse to learn from others.

Need good support for calendars to allow meetings to be easily added.

Decided on fortnightly meetings, but first meeting is scheduled in a month for 2023-05-25T05:00:00Z.
