Volunteers for science talks welcome. If have talk relevant to group please let us know.

@dkhutch has volunteered for 31st August.

Interested in very relevant/important watching a pre-recorded video for a speaker? Be good if it was something that would spark discussion in the group. Need someone to sponsor a talk. @eunpalim saw a talk about high resolution impact on ENSO and southern ocean processes.

Definitely not a regular event. Mostly about filling gaps.

Meeting structure discussion: Working Group seems to divide along between different model development aims:

  1. improving processes and their representation in models
  2. improving performance.

Is it worthwhile to alternate focus of meetings between these two aims to ensure community adequately catered for?

@Dietmar_Dommenget not sure if there is a 50/50 split in the community. Everyone wants to improve models, once have a fast model not such a focus. Can improve model by increasing resolution, or by improving parameterisation. Don’t have to always be interested in specific equations.

@RachelLaw Perhaps split is around the models. A lot to be gained by sharing tools and workflows around models.

Shared experiments/ACCESS-NRI resources

Any proposals for experiments to utilise ACCESS-NRI compute resources?

See the topic for more info.

@Dietmar_Dommenget if can get a modified land-sea mask can use resources. Make for @dkhutch. Relies on getting a breakthrough with configuring the model.

Would be good to have a board displaying all the experiments, and how they are done.

@dkhutch has made a wiki with instructions for making modifications to the ocean model in GFDL CM2.1.

ACCESS-NRI Workshop

Draft program now on ACCESS-NRI website

Breakout discussion should be relevant to more than one area (Working Group).

There is an online spreadsheet where can suggest speakers. There is a slot for a speaker from the ESM Working Group.

Talked to @gpontes, @Dietmar_Dommenget and some others, that would be good to have an hour in the Working Group day toward model configuration modifications, land-sea mask, boundary conditions.

There is some space late additions to working group day if results are available.

Pencil in talk for faster ACCESS Coupled model by @Dietmar_Dommenget. Get paleo group interest.
@dkhutch would also like to present something model development/configuration related with some UNSW colleagues.

Need to feedback to @wghuneke as she is organising the working group day.

@paulleopardi Bureau still pursuing coupled models, maybe get their experience with using Nemo, could be interesting interchange of ideas.

Science talk

@ars599: “The representation of ENSO in ACCESS CM2 and HadGEM3”

Work from his PhD research.
