Meeting Minutes

Introduction, agenda

3. Lévy presents the objectives and agenda of the meeting, presentation available here​

The proposed agenda covers usual items so as discussion on the draft of Development Strategy document Draft available here​, and some discussions on possible improvement of NEMO organisation as discussed in Barcelona. AS introduction to these discussions, two descriptions of NEMO organisation, teams and groups are presented to illustrate the organisation today and the important contribution of NEMO System Team experts today:

NEMO community and consortium organisation	NEMO development groups and teams

The proposed agenda is approved.

1) NEMO System Team brief report on the status of 2017 workplan actions at this date

The 2017 workplan as approved at the beginning of the year is available here. C Lévy presents the status of work today as described by the Six NEMO officers, see presentation here​. The 2017 development work is going on in time to reach the expected objectives by the end of the year.

2) Exchange of information on the existing Working Groups

For each Working Group, its leader to briefly present: a slide on the work done during the past 6 months, a slide on the open issues, i.e. the list of questions to be answered before end of 2017, and a slide on the perspectives for 2018.

AGRIF (J. Chanut)

The list of needed developments and their priority has been build by the working group. The development work now needs to be done (and has been delayed due to lack of ressources and H2020 COPPER project not funded). Still the working group's view on the future is to take the needed time to validate and publish the existing and announced features. Open questions on update of Nesting tools versus Configuration Manager developments.

Configuration Manager (S. Ciliberti)

Robustness and test cases (S. Flavoni)

All the development and simplification is now done inside NEMO First test cases available in NEMOGCM, so as associated tools to build and use them Now need to define the location of all test cases (existing ones build build consortium members, so as future ones coming from the community), so as the acceptable procedure for all to ensure sufficient quality control (including the responsibilities of System Team on one side, and of the developer on the other). Interest expressed (by D. Marshall) to start using test cases for students.

Data assimilation and interface ()

Some inputs have been included in the strategy document, but role and perspectives of this working group are unclear for now, after the decision made concerning TAM, so as the leave of Pierre-Antoine Bouttier from his position.

Parametrisation of mesoscale eddies (M. Bell)

A lot of discussions took place within the group, especially to elaborate important tasks and priorities. Within the GEOMETRIC project now funded, the developments are identified and will start within the next year. Le Working Group proposes to be disbanded.

TOP (C. Ethé, O. Aumont)

No new developments for now, but focus on consolidation of modularity with regards to the different BGC models (PISCES, BFM, MEDUSA...) A meeting on PISCES development, with representatives of BFM and MEDUSA will take place in Paris beginning of July. Scope of WG may be updated afterwards, so as the corresponding section of NEMO Development Strategy document

Sea-ice (M. Vancoppennolle)

Wave coupling (E. Clementi)

3) Discussion on the draft of NEMO Development Strategy version 2017 (C. Lévy)

Draft available here​

• Is the document fulfilling the goal: design NEMO development for the next 5 years?
• What could be improved in the draft?
• How to make the strategy become effective implementation in NEMO reference?

The document appears to be in a good shape for now, i.e. as a complete draft. A number of suggestions are made and will be taken in account by the writing group.

The Developer's Committee believes it would be useful to publish it as open document, especially since it will allow to refer to it in projects, etc... The Developer's Committee will write a message to SC (action J. Le Sommer) to try convincing SC to make it open.

Claire Lévy will ensure the draft is complete and fulfils the suggestions and comments of Dev. Committee. As so, the draft will be considered as approved by Dev. Committee and send (as a draft) to SC for information by end of July.

4) Preparing 2018 and mid-term

Evolutions of Working Groups

Developer’s Committee to make recommendations for each Working Group by the end of 2017. If relevant, list of new Working Groups to be created, and selection of their members

• AGRIF: need to find a unique place where tools to set up AGRIF configuration are developed: to be discussed with Configuration Manager and Test cases WGs: need to make one choice between nesting tools (needing update), future configuration manager, or tools build for test cases
• Configuration Manager: Should focus on the tools to set up NEMO configuration only, and define a strategy with existing resources to decide where to drive the future for next generation, starting from SIREN. Same comment as for AGRIF WG
• Robustness and test cases : Very good job to be continued, focusing on the modality to set up for accepting and distributing test cases. Same comment as for AGRIF WG
• Data assimilation and interface
• Parametrisation of mesoscale eddies: as suggested by WG, it is now disbanded.
• TOP
• Sea-ice
• Wave coupling: change this WG to air-sea coupling, including waves (aligned with Chapter 9 of Dev. Strategy document). Details of proposal to be presented by E. Clementi during next meeting end of the year
