Speakers: Francois Delage can speak on September 28th: “CMIP6 attribution of extremes”. @lynnzhou working on attribution of climate extremes (S2 model) and can talk on 26th October.
Anyone who wants to change the meeting time should comment on the forum topic:
Shared experiments
@Dietmar_Dommenget can’t manage to make the necessary configuration changes to be able to run proposed experiment. Uses “fast” version of N48 (30 years/day). Some tracers have been turned off to make model faster. Might be a changed vertical resolution from CM2.
@eunpalim proposed ACCESS-S2 Experiment to understand influence of atmosphere on last triple La Niña. Don’t necessarily need compute, but storage support required. 1 member takes 1TB. Joint investigation with F&P Working Group . How much interest does ESM WG have for this topic? If compute resource unused, would use some. Minimum requirement would be storage, perhaps shared with Forecasting and Prediction. For 20 ensemble members would require 20TB. A lot of interesting atmospheric events between 2000 and 2022. Related to ozone depletion. And volcanic eruption. There is an idea Hunga Tonga–Hunga Haʻapai eruption allowed La Niña to persist. This experiment is designed to test this. Could start running immediately.
Community members who are interested in this experiment should reply to the experiment proposal to discuss the diagnostics they would need to collaborate and achieve their science goals.
@tiloz WG can request storage for interim until funding stabilised. Likely long-term have 100TB available.
@LaurieM need to answer to @clairecarouge with our requirements. Might need a procedure and policy for for retention of data in the longer term.
ACCESS-NRI Workshop
- Invited speakers are now mostly locked in
- Big focus is now working out how the breakouts will be run
- Sitting at about 100 in person attendees at the moment, registrations will all be extended to midnight 20-Aug (BUT we’re almost at capacity for in person, so register quick if you haven’t)
Program:
2-day workshop will be hybrid, working groups will be limited.
Thursday 7th September ESM Working Group meeting. Half day to join other WG meetings.
Will be two sessions. First session with presentations focussed on model evaluation and development. Can indicate on registration form if you want to present.
Second session will be posters, can talk about anything. Learn about what we do and how we can collaborate.
Registration open until 30th.
Science talk
Romain Beucher, Model Evaluation and Diagnostics Team Lead: “ACCESS-NRI support for Model Evaluation and Diagnostics".

Will be presenting at ACCESS-NRI Workshop. Also running training on the Workshop training day, and will run other trainings in the months afterwards.
- Will be supporting a number of tools, e.g. iLamb, ESMValTool
- Aspire to include analyses from ACCESS Community
- Created “ACCESS-NRI Replicated Datasets for Climate Model Evaluation”: observational data collection at NCI (
ct11). - Created ACCESS Intake catalogue for data at NCI. Dougie Squire will be giving some training on the Workshop training day
Q&A
ACCESS observational data collection is to support the tools. Yes some data already available at NCI, will also be making sure NCI datasets are up to date and in good condition. Some datasets on NCI might be moved or replicated.
Would be good to state if data are original, or interpolated to specific grids.
How are model components prioritised? Tool focussed: ESMValTool to begin with. Mostly ESM and CMIP. Assume CMORised data. Also trying to make tools aware of native model output to CMORise on the fly.
What is monitoring on the fly? Working on a tool to evaluate model output as the model is running. Currently doing basic comparisons. Generating simple plots on the fly. Generalisation of analysis that @MartinDix has done in the past.
