ACCESS-NRI COSIMA 2025 Training Program
Hi everyone! This Friday, the ACCESS-NRI COSIMA 2025 training program kicks off 
with:
Session 1: Building and Using Intake Datastores 
Presenters: Anton Steketee (@anton), Charles Turner (@CharlesTurner)
When: 11am 21 Feb. 2025 (Friday)
Where: Zoom
Description: The ACCESS-NRI Intake Catalog is the preferred python framework now for sharing experiment results and providing a standardised way to load model data across experiments. At this talk we will cover how to create Intake-ESM datastores for individual experiments that are in progress, and how datastores can be used in Jupyter notebooks to load data.
Training Materials: 21st Feb 2025 - Building and Using Intake Datastores
Who should come : Anyone that wants to analyse output from their own or other’s model simulations!
Looking forward to seeing you all there!
Upcoming Session Next Friday 2025-03-06T13:00:00Z 
!
Topic - How to use COSIMA recipes?
Presenters - @CharlesTurner @AndyHoggANU
Please stay tuned to this topic for more details that will be posted next week!
Interested in full program schedule - Click here for the full program.
Help please 
!
The program will be all the richer with community input, and maybe a starting point for new collaborations… Perhaps some of you have an interest in demonstrating or showing off one of your favorite tools, models or analysis?
Examples might include: WW3, panantarctic configs, MOM6 idealised modelling, Oceananigans, regional modelling, evaluation to observations, novel OM2 diagnostics, running isomip+ mom6 etc…
The only criteria is that you think it’s of value to the community. Please get in touch with jasmeen.kaur@anu.edu.au and Chris.Bull@anu.edu.au, or post on the forum.

Hi everyone!
To gather suggestions and ideas for potential training topics for the 2025 ACCESS-NRI Community Workshop (in Melbourne from 8-12 Sept.), the ACCESS-NRI training team has created a poll 
on the ACCESS-Hive Forum.
We would love to hear feedback from all community members about the training sessions they’d like to see this year!
There are 3 main ways to add or vote on the suggestions (similar to StackOverflow):
1. 
Choose up to 10 options from the existing options on the poll.
2. 
Add a new suggestion by hitting the 
button.
3. ↑ You can also upvote any suggestion found in the replies.
We are looking forward to meeting you at the working group meetings as well 
.
Please note that the poll will close on 2025-03-30T13:00:00Z.
Thanks heaps!

Session 4: How to use ESMValTool for observation/intermodal comparisons
Presenters: Felicity Chun (@Flick.Chun)
When: 11am 4th Apr. 2025 (Friday)
Where: Zoom
Description: This session will show the use of ESMValTool to compare data from observations and models. There will be a brief overview of the ESMValCore and ESMValTool packages, finding data for ESMValTool and then we will run through some example notebooks. I will also show a ‘traditional’ run of an ESMValTool recipe and outputs.
Prerequisites
- To use ESMValTool on Gadi you need to be a member of
xp65. - Also any projects for data, these datasets would already be CMORised - join
ct11,fs38,oi10 - Start up a Jupyter session on ARE with:
module directories:/g/data/xp65/public/modules
modules:esmvaltool-workflow - Session materials
Note: Notebooks shown will be shared if you are unable to run at the same time as the session. Short presentation deck with links will also be shared. See here same as above

ACCESS-NRI COSIMA 2025 Training Program
Here we are, with our 5th ACCESS-NRI & COSIMA 2025 training session!
Session 5: Unlocking the Power of Xarray and Dask
Presenters: Jemma Jeffree @jemmajeffree
When: 11am, 2 May 2025 (Friday)
Where: Zoom
Description: Xarray and Dask are increasingly becoming key tools for ocean modellers. However, both vectorisation with xarray and lazy computing with dask remain an enigma to many. This session will explain what happens under the hood of these libraries and provide tips to optimize your code performance. We’ll also walk through the logical steps to transform complicated analyses from for-loops into efficient vectorised functions, using real-world oceanographic examples.
Prerequisites
- Basic familiarity with Python, Xarray, Dask and how to load large datasets.
Note: A brief presentation deck will also be shared shortly before the event.
