Workshop to analyse and discuss the preliminary results of NEMO in CMIP6 - 28 & 29 January 2016 in Grenoble - France

Motivations All the groups involved in the CMIP6 experiments are now setting up and testing their configurations (ESM or forced ocean in OCMIP). For those using NEMO or part of it as ocean, sea-ice and or biogeochemical component, it appears to be useful to share the analysis of their preparatory simulations in order to identify the robust results, the weaknesses and possible improvements.

Goals Comparing results of NEMO in mainly 2 different global resolutions in different experiments, i.e forced or coupled with different atmospheric models can allow us to better understand and hopefully correct some biais by discriminating the adjustments of the coupled mode from the internal errors of the ocean model.

Proposed organisation and agenda A 1.5 / 2 days meeting is suggested, in order to have time to share and discuss the results. Location to be defined depending on the attendees. Meeting should take place after preliminary analysis of a first set of experiments going on now, but earlier enough for each group to take benefits of discussions for the CMIP6 experiments. A date during January/February? 2016 is proposed (could be after DRAKKAR meeting taking place 25-27 January in Grenoble since many expected participants will be there?). Agenda of the meeting should also be discussed: sessions by configuration, by MIP, by open questions (for example: adjustment of vertical parametrization in coupled mode, or coupling frequency...)

Invited groups In order to facilitate extensive discussions on strengths and weaknesses of the results, we propose not to open the meeting widely, but to decide the list of invited groups.
