CNRS-1 - Coupled interface (continuation)
Motivation: OASIS-MCT interface: MPP version of OASIS coupler.
Status : developed and used in PULSATION project

Priority:
Depends on: work done on new IOserver at IPSL
Principal Investigator : Sebastien Masson (smasson@…)
CNRS-3 - Energy diagnostics (end)
Motivation: output 3D trends of tracers, momentum, kinetic energy and potential energy.
Status : almost done (see dev_r3309_LOCEAN12_Ediag ) Finalisation in 2013.
Main tasks :
(1) implement the 3D output of tracers and momentum trends (done with validation in 2012)
(2) compute and output the 3D trends of PE and KE : vvl case to be validated
(3) documentation

CNRS -4 - On-line coarsening of TOP (2 years action)
Motivation: introduce a coarsening of the model resolution on the biogeochemical model (TOP) (Lévy et al. Ocean Modelling, 2012)
Status : Part of the EMBRACE FP7 project. Work started in may 2012. The project duration is 2 years, with 2 deliverables in NEMO: 1st year (2013) : on-line coarsening of the ocean outputs ; 2nd year (2014) : on-line coarsening of TOP
Main tasks :
(1) on-line coarsening of the ocean outputs with a factor of 2 or 3, interfaced with IOM only.

CNRS-5 - reference manuels (continuation)
Motivation: paper documentation, a never-ending story
Status :
Main tasks :
(1) Create the TOP documentation (TRP + interface to bio-model) using Latex (similar to the NEMO ocean engine documentation)
(2) review of the written documentation (NOCS team)

CNRS-7 - Internal evolution of the ocean dynamics
Motivation: improvement of some aspect of the ocean dynamics
Status : conception done
Main tasks :
(1) implicit bottom friction: change the order of call : dynspg 1st, then dynzdf
(2) momentum advection (all dynadv modules, dynspg_ts) : ensure the consistency between non-linear free surface (vvl) and vector invariant / flux form for non linear terms of the momentum equation
(3) horizontal pressure gradient in density anomalie and its impact on dynspg_ts (Marsaleix et al 2008) (all dynspg modules in particular dynspg_ts, dynhpg)
NB: - grouped in one task as they involved common modules
- need not only test cases but also realistic one: ORCA12 with vvl (NOCS).

CNRS-8 - LIM evolution
Motivation: LIM3 as the only sea-ice model in the reference and LIM3 evolution
Status :
Main tasks :
(1) merge LIM2/LIM3 (i.e. LIM3 mono category gives almost same results as LIM2) and remove LIM2 in 2013 or 2014.
(2) optimization: diagnose where it cost the most and try to improve the situation
(3) update of EVP rheology (Bouillon et al 2012s)
(4) LIM3 coupled interface
(5) ice-ocean interface: rewrite from a ice point of view the ice-ocean heat, salt and radiation exchanges ; assess the energy, salt and water conservation.
(6) introduce an arbitrary number of tracers (today only "age")

CNRS-9 - Configuration setting
Motivation:
- whole namelist in all standard configuration: heavy to make any changes, diffucult to see the specificities of a configuration, and default values for namelist hard coded in the code, but never used ! ==> Standard namelist at CONFIG/namlist, the namelist in CONFIG/MY_CFG/EXP1/namlist only contains the changes from default value
- global model size not in the namelist but still in many par_....h90 ==> put all this in the namelist
- several old non-doctor namelist variable names still in the code ==> to be suppressed
See Configuration_Setting page for more detail

Main tasks : see the motivation

No man power for the following items:
1 - z-tilde coordinate
Motivation: introduce an arbitrary lagrangian eulerian coordinate to reduce spurious diapycnal mixing due to high frequency vertical variations
Status : done in a phd thesis, see Leclair 2010 ; a 2011 branch exists: see here
Main tasks : update for the new NEMO version
2 - compact vertical advection scheme
Motivation: Compact schemes have the particularity to be of high order but compact in space
Status : Developed for NEMO version 3.1 (L. Debreu)
Main tasks : adaptation to current version ; validation and documentation
3 - KPP scheme
Motivation: KPP (K profile parametrization is widely used in ocean models to compute vertical mixing coefficients. Current version implemented in NEMO is old and unmaintained, furthermore, KPP has been redesigned for ROMS model to improve the regularity of the solution (better numerics)
Status : Implemented in ROMS (UCLA) by F. Lemarié et al. (Ocean Modeling in press)
4 - Rotated bilaplacian
Motivation: Rotated biharmhonic diffusion operator. This we would be able to use it in the isopycnal direction, and this operator would also be particularly suitable for s-coordinate
Status : Implemented in ROMS (UCLA) by F. Lemarié et al. (Ocean Modeling in press)
