1. Welcome and approve of the minutes

https://github.com/wmo-im/et-acdm/wiki/ET%E2%80%90ACDM-2026%E2%80%903:-17-March-2026 Agenda and minutes approved.

Action: open issues/perspectives from April GAW Symposium meeting (data centre challenges, future plans, etc.) to be carried forward and put as a dedicated agenda item for the next meeting for a more formal discussion.

2. GAW Secretariat updates

Discussions in the SSC EPAC about restructuring of groups:

  • Current structure has ~19 groups; there is a clear direction to reduce this number
  • Proposal to combine Data Management with Measurement Quality into a new group (name still to be decided) dealing broadly with data quality and data exchange for atmospheric composition
  • Feedback has been received from members of this expert team, from the Measurement Quality group, and from other SAGs/ETs
  • No final implementation plan yet; discussions ongoing; nothing is fixed “forever” or even for the next four years

WMO's Task Force

  • WMO created a task force (with representation from different countries and the WMO Executive Council) who examined: Essential areas/Less essential areas/Areas to be put on hold
  • They produced an Excel-based recommendation to the Secretariat
  • Further clarity expected around/after the upcoming Executive Council meeting (22-26 June)

Funding and staff changes

  • US funding remains uncertain; as of the meeting, funding had not yet been received, though business is expected to continue “as usual” for 2026.
  • Julie (Secretariat colleague) is leaving; next week is her last week.

CAMS25 project & EUBREWNET

  • CAMS25: project creating an interface to monitor GAW network.
  • Currently stuck at legal level with Copernicus.

EUBREWNET / MOU:

  • MOU signature with AEMET was also delayed for months, but is now ready to be signed.
  • EUBREWNET is a data processing network for total ozone column (Brewer spectrophotometers) and is to become a GAW Contributing Network.

3. GAW Symposium, feedback

A round-table to capture feedback on the recent GO/GAW Symposium:

  • Difficult to attend online due to time zone differences.
  • Engagement with Oksana’s sessions on donor and philanthropic funding.
  • Interest in feedback on Jörg’s presentation on this group and on impressions from the poster session.
  • A good but long meeting, suggestion for structuring the programme to make it easier for some participants to attend only 2–3 days with targeted content.
  • Appreciated deliverables related to interoperability and AI readiness.
  • Presentations scientifically interesting, splinter ET-ACDM meeting had fewer people but high-quality discussion.
  • Difficulties with the breakout sessions, complicated remote access and lack of communication.
  • Suggestion for the future: 2–3 hours of core/controlled sessions per day, and the rest of the time for informal networking, which is often where: Common interests are identified/New ideas and collaborations arise.
  • Secretariat responded the reasons to make the symposium substantial were: Last in-person symposium was in 2017/Participants coming from all over the world was a unique opportunity to grow the GAW 'family'.
  • Strong resonance on the talk about AI and data management. Conclusion: ET-ACDM risk becoming obsolete if does not contribute to AI-related discussions.
  • Stressed that the group should actively rethink guidance for data management under AI.
  • Some existing standards (e.g., very strict controlled vocabularies) may become less central.
  • Concepts like persistent identifiers remain important but might play a different role.
  • Observed that AI tools do not handle very deep JSON structures well (better with simpler formats such as CSV)
  • ET-ACDM should focus on making data and metadata AI-/LLM-ready, e.g., for workflows like MCPS.
  • Support for using AI for discovery and assistance, but governance requires human-controlled notations, labels, and descriptions for variables.

4. Reviewing and closing open issues

https://github.com/wmo-im/et-acdm/issues/26

Actions:

To decide which KPIs will be included, in particular if to include 'variable years download rate'

To suggest a KPI for the uniqueness of records

To decide if to include a KPI on DOI-based impact

https://github.com/wmo-im/et-acdm/issues/32

The new GAW IP can be discussed further ahead.

Both #29 & #30 issues will be closed:

https://github.com/wmo-im/et-acdm/issues/30 https://github.com/wmo-im/et-acdm/issues/29

#28 to be closed:

https://github.com/wmo-im/et-acdm/issues/28

#27 to be closed with the comment:

Noting that no concrete endangered datasets were identified, except some concern about the precipitation data centre (to be followed up by the relevant SAG). Referencing examples of de facto contingency (e.g., WDCGG harvesting AGAGE).
