CNRS-0 - Lead discussion on code simplification - see shared actions

Motivation: System simplification: as discussed during the exercice of prospective, the system needs a simplification to better evolve (and reduce its maintenance)
Status : on going reflexion
Main tasks : agreement (consensus) on what can be removed and then remove it. See foreseen simplification here
Science Reviewer:
System Reviewer:
Deadline: end 2014
Priority: high
Depends on: dev. committee' agreement
Principal Investigator : Gurvan Madec

CNRS-1 - TEOS10: new equation of state

Motivation: move to TEOS10 ; add a simplified EOS ; remove existing EOSs
Status : both equations have already been tested in ORCA2-LIM
Main tasks :
(1) simplify equation of state (4 terms associated with temperature, salinity, cabbeling and thermobaricity, reap.)
(2) TEOS10 for a boussinesq fluid (conservative temperature, new definition of salinity)
(3) remove the existing equation of state (require dev. committee' agreement)

Deadline: summer 2014

CNRS-2 - Investing in AGRIF expertise - see shared actions

Motivation : Hands on AGRIF for xx test cases. Gathering and sharing expertise. Towards a NEMO-AGRIF tutorial/training course.
To be elaborated with other members of the consortium (making AGRIF compatible with split-explicit time stepping, s- and z-tilde coordinates, sea-ice...)
Status :
Main tasks :
(1) use of AGRIF in coupled ocean-atmosphere and coupled oceanic configurations
(2) contribute to the shared expertise by building a tutorial/training course
(3) write a documentation of the NEMO interface to AGRIF
(4) salve the issue of AGRIF with TKE (and GLS) vertical physics at the Equator

CNRS-3 - LIM evolution including LIM3+AGRIF

Motivation: simplification (only LIM2 in the system) and improve
Status : continuation
Main tasks :
(1) LIM3 in mono category able to reproduce LIM2 behavior.
(2) assessment of LIM3 with AGRIF (EVP rheology only)
(3) on-line check of ice-ocean mass, heat and salt fluxes and ice budget
(4) Suppress LIM2 (require (1) & (2) to be done)
(5) management of land fast ice (needed for embedded sea-ice)

Deadline: end 2014
Priority: high
Depends on:
Principal Investigators : Clément Rousset, Simona Flavoni & Martin Vancoppenolle

CNRS-4 - Biogeochemical tracers in sea ice

Motivation : prepare the introduction of a full BGC model in LIM3
Status : starting project
Main tasks : In 2014, Case of constant tracer concentration in the ice. Add "just" tracer fluxes between ice and ocean, not an advection of passive tracers in LIM3

CNRS-5 - TOP Online coarsening

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 ( done ); 2nd year (2014) : on-line coarsening of TOP
Main tasks : On-line coarsening of passive tracers at least for the numerics & physics used in ORCA025.

CNRS-6 - TAM

Motivation: Now that code has been updated, add the tools and configurations for the projects
Status : Postponed from 2013
Main tasks : Reference configurations, tools for parameters estimations…as an incitation for projects
Science Reviewer:

Deadline: end 2014

Depends on: none
Principal Investigator : Pierre-Antoine Bouttier

CNRS-7 - COMODO test cases

Motivation: imrpove NEMO's reliability validation and allow better models comparison
Status : Cont. 2013
Main tasks : Decide which test configurations (including those valuating some of the NEMO abilities, to be discussed with INGV -Paolo Oddo also)
Finish the implementation/testing/validation work. At least 2 COMODO cases : 2D upwelling (Simona) and channel (Julien Jouano)

CNRS-8 - Coupling interface

Motivation: system simplification Status : Start Main tasks : Suppress OASIS3, replaced by OASIS-MCT (loose compatibility with OASIS3) Science Reviewer: System Reviewer: Deadline: end 2014 Priority: Depends on: Principal Investigator : Sébastien Masson

CNRS-9 - Global ocean global configurations for next ESMs

Motivation: start setting up the new generation of ocean component for ESMs: ORCA1/ORCA025
Status : Start
Main tasks : Contribution to definition of ORCA-1 and 025, and first reference simulations.
Starting by a forced simulation ORCA1-LIM3 - non linear free surface, embedded ice, Griffies isoneutral and maybe GLS

Deadline: end 2015
Priority: high
Depends on: LIM3 evolution, and checking all existing pieces together...
Principal Investigator : Claire Lévy

CNRS-10 - Energy diag.

Motivation: Finalize trends diagnostics (3D trends of tracers, momentum, kinetic energy and potential energy)
Status : Continuation of 2013
Main tasks :
(1) implement the 3D output (using xIOS) of tracers and momentum trends (done with validation in 2013)
(2) compute and output the 3D trends of PE and KE : vvl case to be validated
(3) documentation
System Reviewer:
Deadline: end 2014
Depends on: the introduction of TEOS10 (for dynamical potential energy)
