Hello COSIMA :wave:

Our next meeting is on tomorrow (Thursday 29 May) at 1130 :white_check_mark:

This week we’ll hear from Aditya Sengupta (Uni Melb) who will be presenting on “Potential role of long-term Southern Ocean warming on sustained weakening of Pacific SST gradient and Walker Cell Strength in ACCESS-ESM1-5”.

Other business:

We ran out of time last week to talk about these two items, so they are on the agenda for this week:

Do you have anything to add to the agenda? Let me know.

As always, the meeting will start at 1130.

:ocean: ACCESS-NRI COSIMA 2025 Training Program

The next session is on TOMORROW and it’s all about visualisation!

Session 6: Visualising the Southern Ocean using ACCESS-Vis - using 3D graphics tools to animate sea ice, current and other features from ACCESS model outputs in the Antarctic region

:disguised_face: Presenters: Owen Kaluza @OwKal
:alarm_clock: When: 11am, 30 May 2025 (Friday - tomorrow!)
:house: Where: Zoom

:teacher: Description: An introduction to ACCESS-Vis and ACCESS-Visualisation-Recipes, the example-driven set of visualisation tools and workflows we’re developing for working visually with ACCESS model outputs and other earth-systems datasets. These tools use GPU powered 3D graphics techniques which have the advantage of allowing rapid rendering of large amounts of data to assist in analysis as well as animation tools to bring data to life in 3D for communication and outreach.

I’ll talk briefly about what is released so far and the tools and examples available on our Github, then run through a more in-depth example demonstration to visualise data in the Southern Ocean that will hopefully be relevant to COSIMA, which I’ll also share as a reference.

:laptop: Prerequisites

  1. Familiarity with Python, Jupyter, Xarray and Numpy

Next Session 2025-06-13T01:00:00Z :next_track:!

Presenters - @aekiss and @minghangli

Please stay tuned to this topic for more details that will be posted soon!
