CONFIGMAN-1 / MERCATOR-1 - Configuration manage robustness and imoprovment

Motivation: A configuration manager demonstrator (SIREN) was added to NEMO TOOLS. Some bugs were fixed this year. Now those code should be agreed and tested.
Status :
Main tasks :

-only SIREN routines will be modified
-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)

Deadline: end of 2016
Priority:high
Depends on:
Principal Investigator : Julien Paul <julien.paul@…>

Config Man?-3 / MERCATOR-2 - SIREN user test

Motivation:

-submit SIREN to NEMO user to be tested
-get feedback from user

ROBUSTNESS-8 / MERCATOR-4 - Improve split-explicit free surface

Motivation: There are several aspects that need to be investigated concerning the robustness of current split-explicit algorithm:

-Tracer conservation issues (all time splitting options do not ensure global and local tracer conservation).
-Missing correction terms in the barotropic equations relative to internal pressure gradients. This would reduce mode splitting error, hence improve stability.
-Work on the stability of barotropic time stepping (based on INRIA's work) to possibly remove time filtering of barotropic variables. This would limit the temporal dissipation and greatly ease online coupling of nested domains at barotropic level (with AGRIF).

ROBUST-9 / MERCATOR-5 - test NEMO3.6 with global configuration

Motivation: Model configurations need to be validated before the release of the model.
Status : ORCA025_LIM2, ORCA025_LIM3, with filtread free surface or time splitting is already running at Mercator,vvl

-LIM2 vs LIM3
-GLS vs TKE
-time-splitting vs filtred free surface
-vector form vs UBS for momentum advection
-run ORCA025 with Z*
-run ORCA12 with time-splitting/LIM2/GLS/UBS?
