**Please submit agenda requests** ESMValTool community workshop 11-13 May 2026

[alistairsellar]

Dear ESMValTool community and @ESMValGroup/esmvaltool-developmentteam,

The next ESMValTool community workshop will take place 11-13 May 2026. The workshop will be held at the Met Office in Exeter, UK, with online participation available also. Registration for the workshop is now closed. The agenda is under development. Please reply to this discussion if would like to suggest additional topics for the agenda.

ESMValTool is a community diagnostic and performance metrics tool for evaluation and analysis of Earth system models. ESMValTool workshops are for the whole community, to participate in discussions that shape the future of our community, and to work with ESMValTool to evaluate and analyse climate model data. The workshop schedule will have discussions in the (UK/EU) mornings and coding / drop-in sessions in the afternoons where you can seek help from experienced users and developers.

The focus of this workshop will be getting ready for evaluation and analysis of CMIP7 data. So please join us if you plan to use CMIP7 data and would like to take advantage of ESMValTool’s multi-model support and powerful data processing capabilities.

Visiting the UK
From the UK government website: “Most visitors travelling to the UK need an ETA or a visa... You usually need an ETA rather than a visa if you’re from Europe, the USA, Australia, Canada or certain other countries.”
You can use this site to check whether you need an ETA or a visa: https://www.gov.uk/check-uk-visa.
Please contact Alistair Sellar if you have any questions.

Travelling to Exeter
The Met Office website has useful information about travelling to our Exeter office:
https://www.metoffice.gov.uk/about-us/contact/how-to-find-our-offices#Exeter
The Met Office is about 5km from the city centre. There are 3 hotels within 2km of the office. However, buses in and out of the city centre are more reliable in the day time, so if you plan to socialise in the evening (!?) I would recommend staying at one of the many hotels in the city centre.

Thanks,
Alistair on behalf of the ESMValTool Steering Group

Here are some topics I could give a talk about:

• Introduction to using CMIP7 data with ESMValTool Add preliminary CMIP7 support ESMValCore#2935
• Configuring data sources and the emerging support we have for data in cloud-native formats Intake-ESM Integration based on #1218 ESMValCore#2690, Add xcube support ESMValCore#2917

[bettina-gier]

Considering the topic, if you want some ideas for the more practical parts of the workshop: It's been brought up several times that a lot of our recipes are still based on CMIP5 data. We could identify a few that we want to use for CMIP7 and then see if they work out of the box or if some diagnostics need tweaks for the expected CMIP7 data format (or live testing with data if any are available by then)

[bouweandela]

If we have no CMIP7 data available yet, we can fake some CMIP7 data by using the Simple_recmorise_cmip6-cmip7.ipynb notebook to CMORize some CMIP6 data according to the CMIP7 standards.

[bouweandela]

It would be nice to put some focus on the REF recipes too. Especially regarding the timerange for the CMIP7 historical period (until 2021 instead of 2014) and the use/availability of reference observational/reanalysis datasets.

Requests by the UET:

• One slot in the plenum to discuss UET updates and recent requests, e.g. ESMValTool tutorials
• Dedicated meeting (1hour) for the UET to align on specific improvements of the tutorial and allocate coding tasks for the workshop

[LisaBock]

Please schedule UET-related topics preventively for Monday or Tuesday, as I might not be around on Wednesday.

There are already some styles planned for IPCC AR7 figures public, e.g. icons, color maps: see IPCC-AR7-WG1/figure-design can we link/include them?
