ACCESS Oversight Committee - Notes from the 22nd October 2020


$7.6m has been allocated over 3 years starting on 1 July. Department has contacted ANU DVCR (Keith Nugent) as ANU is likely host. Early steps will likely be to appoint a director and a governance model made up of partners. Proposed A. Hogg contacts K. Nugent to make him aware of AOC if any input from this group is useful. This group could be replaced by NRI governance. It would be good if communities of interest organise themselves to reach common view of infrastructure needs.

2. Round-table - update on activities and issues relating to ACCESS


  • Charmaine replacing Tony on AOC. Tony thanked for his contribution.

Universities (including STRESS2020 high res simulation)

  • Working through research plans now that ACCESS-NRI decision known.
  • Mid-term review went well.
  • ACCESS CMIP6 versions training run on 20th October was helpful
  • Dataset from 400m simulation being prepared for release. Workshop likely.

CSIRO (including ALCG simulations)

  • The ACCESS lightning-produced NOx work is out in ACPD now: and the new lightning scheme has been committed to the UM trunk: see ticket
  • As part of the Australian Antarctic Program Partnership, work is being undertaken on improving the Southern Ocean radiation bias in the UM by improving the representation of marine aerosol and cloud processes. We are collaborating closely with UK Met Office, NIWA, and others on this activity.
  • AMOS 2021 conference workshop on ACCESS-CMIP6 models is expected to go ahead assuming sufficient interest


  • CMIP publishing taking significant time. NCI contribution is much appreciated by CSIRO.
  • Visualisation progressing. Discussion on whether this can be more coordinated across ACCESS (e.g. video that shows range of applications). Noted that included in NRI.
  • ERA5 – announcement of user access not far off – early November. Takes time to get data from ECMWF.
  • HPC roadmapping / NCRIS – NCI asked to do some more work/engagement – so good to be clear about what we need for our models.
  • Pawsey announced next machine, AMD CPUs and GPUs. Late 2021-2022 delivery. Not much storage. Couldn’t run ACCESS on GPUs, not sure about balance of CPUs.


  • OMIP runs published soon – not quite same version as ESM1.5/CM2 – so new institution-id/model-id for ESGF. Also publishing IAV forced 1/10 model. No news yet on COSIMA2.


  • A “Getting Started with ACCESS-CM2 and ACCESS-ESM1.5” (CMIP6 configurations) training session was held (20 Oct) for potential new model users. There were 64 attendees from across CSIRO, BoM and universities. A recording of the presentation, along with documentation and the meeting slides are available via the NESP Earth Systems and Climate Change Hub website
  • CMIP6 ESGF downloads:
    • ACCESS-ESM1.5 +2M downloads, ranked 15/135 CMIP6 models
    • ACCESS-CM2 +1M downloads, ranked 25/135 CMIP6 models
  • NESP ESCC science symposium 8-9 Dec around research achievements from the Hub. Partly face-face (1 site per State). [did not go ahead]
  • Consultation draft for Next Gen projections – targeted distribution for feedback. Collated information (e.g. across CLEX) useful.
  • David K – last meeting. Thanked.

UM Partnership activities

  • Each partner has nominated at least one Next Generation Modelling System (NGMS) champion to facilitate planning of uptake/transition to NGMS from UM. Local champions are Justin Freeman and Joerg Henrichs (BoM) and Peter Dobrohotoff (CSIRO).
  • UM Users workshop is Nov 9-12 (evenings for Australia)
  • Given surplus UM Partnership fees (no travel), the Partnership will fund secondments for LFRic transition support and Evaluation Tool/software portability. Partners have been asked to propose suitable staff who could make full or part time contributions over 1-2 years.
  • GC4 Assessment workshop will be taking place 2-3 Dec 2020,
  • Interaction of UM partnership with ACCESS-NRI will be important as ACCESS-NRI is developed.

Other business

  • Next meeting 10th December
