MERCATOR.1 — Improvement of OBCs: end of 2011 task

Motivation: participate to merge of OBC and BDY; work on atmospheric pressure and tide forcing in the new package
Status : --
main tasks : --
Principal Investigator : Jerome Chanut (jchanut@…)
Deadline : --
Priority: High
Science Reviewer : --
System Reviewer : --
Number of weeks : 4 (TBC)

MERCATOR.2 — PPM advection scheme

Motivation: Add another scheme for tracers advection: horizontal part. Vertical part will be made by NOCL.
Status : Running on NEMO_3.2.
main tasks :review.
Principal Investigator : Guillaume Reffray (greffray@…)
Deadline :
Priority: Low

Number of weeks : 2

MERCATOR.3 — resolving the 2 versions of time-stepping

Motivation: Tracer conservation and time splitting. reference: Shchepetkin, A. F., and J. C. McWilliams?, 2005
Status :Running in NEATL36 at Mercator.
main tasks : Main idea:replace Leapfrog scheme by a Fb tamporal scheme, but keep actual method for updating ssh at 3D time-stepping.
workplan:
1.test some eventual problem of divergence of SSh in barotropic mode compared to SSH in 3d mode ( cf Hallberg and Adcroft, OM 2009: Reconciling estimates of the free surface height in Lagrangian vertical coordinate ocean models with mode-split time stepping).
2.implementation in NEMO_3.3 of this time-splitting.
3.test in high-resolution configuration at Mercator.
4.take a decision for reorganization of step for time-splitting.
Priority: High
Principal Investigator : Clement Bricaud & Jerome Chanut (jchanut@…)
Number of weeks : 4 (TBC)

MERCATOR.4 — implementation of OBC's schemes for PISCES

Motivation: Use new package ; implement new methods.
Status :

Number of weeks : 2 (TBC)

MERCATOR.5 — Solar flux filtering at daily frequency to force biogeochemistry model.

Motivation: For coupled model ( physic + bio ): physic needs 24 hours (+ diurnal cycle) or 3 hours solar fluxes, but bio need a 24 hours mean.

aditionnal work:

adaptation of PISCES to the VVL : compare work done by Guillaume Reffray with work done by UK Met Office.
