CNRS-4 - Stochastic parameterization of the effect of unresolved scales in the equation of state

Motivation: Unresolved scales have been shown to produce an important effect on the horizontal density gradient through the non-linearity of EOS (Brankart, 2013).

(2) Test and validate on reference configurations

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

CNRS-16 - LIM3, FCT4 advection scheme

Motivation: Rachid, using a classical test case of advection of a passive tracer, have shown that a 4th order Flux Corrected Transport (FCT4) had a behavior very close to the one of a Pather scheme, i.e. the one used in LIM. It is much cheaper as you don't have to advect second order moments in addition to the field itself.
Status : The FCT4 scheme has been coded and tested as part of a 3D advection scheme for ocean tracers.
Main tasks : adapt to LIM3 and test it. If it performs as expected, implement it is the current version of LIM3

CNRS-17 - Vertical redistribution of salt rejection due to ice formation

Motivation: Introduce the sub-grid-scale brine rejection parameterization proposed by Nguyen et al JGR2009. Such a parameterization tends to reduced the mixed layer depth below sea-ice (which is generally to large). Improve the parameterization by taking into account the velocity difference between ice and ocean.
Status : Already coded and tested in v3.4 with ORCA1-LIM3. Ocean Modelling paper in revision (Barthélemy et al. 2014)
Main tasks :adapt to the current version
