MERCATOR-1 - Configuration manager: 9 - NEMO validation and contours of user support

MERCATOR-2 - Data Assimilation Interface: SLA model equivalent: 6 – The assimilation component of NEMO

MERCATOR-3 - Bugs on ORCA025 and ORCA12 grid on the north pole

MERCATOR-4 - AGRIF + time-splitting compatibility: 5 – Towards locally higher effective resolution

MERCATOR-5 - Implement quasi-hydrostatic approximation : 4 – The ocean dynamics component of NEMO


MERCATOR-1 - Configuration manager

Motivation: Easily manage the set-up of new-configurations.
Status : Preliminary version available in Sept 2013. Fortran routines only.
Main tasks : Develop tools (scripts, Fortran routines, graphical interfaces) to create inputs needed to run a new configuration. Take into account online (AGRIF) or offline nesting. Tasks scheduled in 2014: Debug, Enable creating a configuration around the North Pole, ensure compatibility with existing nesting tools interface. Possible future developments in 2015 and beyond: Vertical remapping (or should it be online ?), Python scripts (?), graphical interface (?)

MERCATOR-3 - Bugs on ORCA025 and ORCA12 grid on the north pole

Motivation: see ticket 637
Status : Continuation

Deadline: Aug 2014
Priority: high

Principal Investigator : Clément "Daddy" Bricaud

MERCATOR-4 - AGRIF + time-splitting compatibility

Motivation: Enable AGRIF and time splitting
Status : Not started yet although some work done in 2008 by F. Dupont (Env. Canada) has been reported in tickets 106 and 107.
Main tasks : This would be done in two steps, spanning two development years:

  1. First, implement basic coupling of the barotropic mode at the baroclinic step level (Similar to what has been done by Penven et al. (2006) in ROMS).
  2. Second, implement full coupling at the barotropic time step level (Debreu et al., 2012)

In any case, try to ensure volume conservation (relying on the forward nature of barotropic equations with time splitting).

Deadline: 2015
Priority: Medium
Depends on: xx
Principal Investigator : Jérôme Chanut

MERCATOR-5 - Implement quasi-hydrostatic approximation

Motivation: Partially relax hydrostatic approximation to restore some important physical properties. See what happens in global eddying simulations.
Status : Not started yet.
Main tasks : Changes are far less computationally expensive than turning to the full non-hydrostatic equations. These would however be significant. Quoting Marshall et al. (1997): "the quasi-hydrostatic model retains cos(latitude) Coriolis terms in the zonal and vertical momentum equations, neglects Dw/Dt? in the vertical and does not make the shallow atmosphere approximation".
Science Reviewer: TBD (Gurvan ?)
System Reviewer: TBD
Deadline: 2015
Priority: Low
Depends on: resources available after completion of tasks above
