AGRIF

AGRIF-1 / Met Office - Increased vertical resolution with AGRIF

Motivation: Vertical grid refinement in NEMO would be a useful tool in simulating some aspects of the ocean (e.g. overflows)
Status: Started in 2015 but much more work to do

HPC

HPC-1 / CMCC/Met Office - Suppress global communications

Motivation: Removing global communications could help improve the speed of NEMO
Status: Not started
Main Tasks: Silvia Mocavero to investigate which communications could be safely removed. Tim Graham to look at a more efficient implementation of functionality in stp_ctl.

HPC-2 / Barcelona - Gather communications ===

Motivation: Grouping communications (lbc_lnk) together is more efficient than several separate lbc_lnk calls.


Status: lbc_lnk_multi in 3.6
Main Tasks: Extend functionality of lbc_lnk_multi to 3D (or 4D variables). Find calls to lbc_lnk that can be replaced with lbc_lnk_multi.

HPC-3 / Barcelona - Suppress useless communications ===

Motivation: Suppress unnecessary calls to lbc_lnk.


Status:
Main Tasks: Use a script to search for and test impact of removing lbc_lnk calls from the model code. Determine whether communications used for diagnostic purposes can be suppressed.

Configuration Manager

ConfigMan-1 / MERCATOR - SIREN improvement and robustness

Motivation:

  • test SIREN code (working group members and maybe some external users)
  • extract from NEMO the meshmask creation (Mercator-Océan)
  • main program (python) to manage all SIREN codes (Mercator-Océan)
  • improve documentation readibility, and add tutorial (Mercator-Océan)

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.
