Color(lime,WARNING page currently in progress)?

Actions on system simplification towards 4.0 can be find here : https://forge.ipsl.jussieu.fr/nemo/wiki/2014WP/2014_SystemSimplification_v2

The status and details of the work already done by Gurvan is located here :https://forge.ipsl.jussieu.fr/nemo/wiki/ticket/1593_CNRS9_NOC3_LDF

HPC actions listed below are the list of required actions. What we can do this year remains to be determined. See Seb's document for more details : https://forge.ipsl.jussieu.fr/nemo/attachment/wiki/WorkingGroups/NEMO_HPC/HPC_tasks_Masson.doc

Wave Coupling

WAVE-1 / INGV - Improvements in wave-current interaction processes implementation

Motivation: INGV is responsible for the WAVE-WG and will continue improving the wave-current interaction processes implementation according to the WG needs.
Status : Implementation of some of the identified processes has been started in 2014 and 2015. To be continued in 2016
Main tasks : Continue the implementation of already defined wave-current processes, if not completed in previous year. Meeting organization with the WAVE-WG to discuss further issues to be investigated and implemented:

• Vertical mixing enhancement due to wave breaking;
  
• Contribute to the discussion on implementation of Langmuir circulation;
  
• Contribute to the discussion on wave-sea ice coupling; ;
  
• others if agreed by the WAVE-WG.

WAVE-2 / INGV - Definition of wave-current interaction processes at small (coastal) scale

Motivation: According to the WAVE-WG, in order to achieve a full wave-current coupling, the small (coastal) scale processes need to be investigated.
Status : To be continued in 2016
Main tasks : Contribute, within the WAVE-WG, in the analysis of this issue in order to finalize the discussion started in 2014 before proceeding with any new implementation

ROBUSTNESS

ROBUSTNESS-1 / CNRS - INTEGRATION OF THE SEABASS CONFIGURATION AS A TEST CASE

Motivation: SEABASS is the reference configuration for Data Assimilation, included in the NEMO v3.4_STABLE version. Various data assimilation experiments have been done with this configuration, with various data assimilation systems (e.g. Cosme et al, 2011, Bouttier et al. 2014, Yin et al., 2014). In this context, this configuration appears to be useful for data assimilation users, to couple their own DA system on NEMO and compare their results with thgose obtained on this configuration. SEABASS is also easy to take in hand. Also, it allows to update the configuration status to the future version of NEMO. For these reasons, this configuration is a relevant test case for Data Assimilation.
