ACCESS Workshop Cryosphere WG Meeting 2024 Discussion Thread

Cryosphere Working Group
1

Hi all,

Please feel free to use this thread for comments about the discussion for the 11:30-13:00 session where we discussed the ACCESS ice sheet modelling team, ACCESS-ISSM development and the WG community plans.

Cryosphere modelling discussion (feel free to edit!)

  • Lenneke showed Mike’s slides about python API and infrastructure for ISSM running, analysis
  • Land surface coupling challenging – how to connect to atmosphere, albedo, lots of communication needed EARLY with land WG
  • What datasets does ice sheet need for other working groups and what can the ice sheet provide? A priority list needed
  • Connect with paleoclimate (ESM) community as they are interested in ice sheet changes too
  • Interaction with solid earth also challenging with UM, orography, coastlines may not be able to change
  • Suggestion of ISSM training 2 day workshop – ISSM friendly and helpful, important to build that collaboration
  • Aim to build community of ice sheet modelers, even amongst non-ISSM users, since it’s a small ice sheet modelers community at the moment.
  • What kind of experiments/projects do people run – standard control runs, perturbations (like cosima?), or more individual runs. This guides what useful infrastructure is needed
  • Easy-to-run infrastructure for honours students to just start running models or analysing data easily. ACCESS-NRI plays a role in this
  • Analysis cookbook – mismip and misomip as an example? Obtain from international users if no Australian runs?
  • Centrally coordinated forcing data very helpful for the future (benefits all ice sheet modellers)
  • Cataloguing important of results using intake catalogue
  • AAD data library exists
  • Multimodel is a strength, seen also in ocean and land communities, especially for science questions, where some models are better at different things e.g. process studies. Want to continue connecting entire ice sheet community even if using different models
  • However, sensible to target ISSM as a future Australian capability
  • Idea that community should keep trying to keep entire ice sheet modelling community connected with focus on research rather than only focus on ACCESS model – what is this ACCESS-NRI CMWG exactly and how does it connected to the entire ice sheet modelling community in Australia (is it a subgroup?). Who is the audience for the CMWG meeting and can we expand the audience of seminars relevant to a broader group of people? Invite other parts of cryosphere and science techniques e.g. obs in meetings too.
  • Benchmarking software is something ACCESS-NRI might be able to help with? ESMValTool for ice sheets – hard with the different ice sheet grids?
