MERCATOR.1 — Atmospheric pressure: end of 2010 task

Motivation: Use Atmospheric pressure to add the atm gradient to add inverse barometer to OBC and BDY. running with time-splitting
Status : Running at Mercatoron 2.3; coded in NEMO_3.2 .
main tasks :test on POMME configuration,review and commit.
Principal Investigator : Jerome Chanut (jchanut@…)
Deadline :??
Priority: High
Science Reviewer : Met Office (TBC)
System Reviewer : Met Office (TBC)

Number of weeks : 2

MERCATOR.2 — Tidal potential

Motivation: add tidal potential, add tidal for key_obc case, converge Mercator and Metoffice codes for astronomical functions.
Status : Running on NEMO_2.3 .
main tasks : NVTK, doc,review,commit.
Principal Investigator : Olivier Legalloudec <olegallou@…>
Deadline :??
Priority: High
Science Reviewer : Met Office (TBC)
System Reviewer : Met Office (TBC)
Number of weeks : 3

MERCATOR.3 — Mixed Implicit/Explicit? bottom friction

Motivation: Unconsistent bottom stress in 2d and 3d modes. From BOM code. Explicit bottom stress in barotropic equations/implicit in baroclinic equations. Adapted for tidal configurations.
Status :Running in NEATL36 at Mercator.
main tasks : NVTK, doc,review,commit.
Principal Investigator : Jerome Chanut (jchanut@…)
Deadline : ??
Priority: High
Science Reviewer : Met Office (TBC)
System Reviewer : Met Office (TBC)
Number of weeks : 2

MERCATOR.4 — PPM advection scheme

Motivation: Add another scheme for tracers advection: horizontal part done at Mercator ; vertical part from UkMet? ? .
Status : Running on NEMO_3.2.
main tasks :.

System Reviewer : Met Office (TBC)
Number of weeks : ??

MERCATOR.5 — ECUME bulk formulae

Motivation: Ability for NEMO to use another bulk formulation for heat, humidity and momentum at the air/sea interface based on multi-campaigns in situ measurements.
Status : Development and phasing with nemo_3.2 OK.
main tasks : NVTK, doc,review,commit.
Principal Investigator : Gilles Garric (ggarric@…)
Deadline :??
Priority: Low
Science Reviewer : Met Office (TBC)
System Reviewer : Met Office (TBC)
Number of weeks : 3

MERCATOR.6 — Lagrangian Floats Module improvments

Motivation: Online monitoring of water particles (position + (T,S) signature), improvements of ascii output + implementation of I/O Ariane (B Blanke) convention: on-mesh initialisation+ netcdf outputs
Status : Working with IOIPSL, not with IOM
main tasks : Phasing with new IOM, NVTK, doc,review,commit.
Principal Investigator : stephane LAW CHUNE (slaw@…)
Deadline :End October 2011
Priority: Low
Science Reviewer : NOCS(TBC)
System Reviewer : NOCS (TBC)
Number of weeks : 1

Motivation: diagnostic
Status : OK for NEMO 3.1
main tasks : review, NVTK, doc and commit
Principal Investigator : Clement BRICAUD (cbricaud@…)
Deadline :???
Priority: Low
Science Reviewer : Met Office(TBC)
System Reviewer : Met Office(TBC)
Number of weeks : 1

MERCATOR.8 — 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.implementation in NEMO_3.3
2.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).
3.test in high-resolution configuration at Mercator.
4.take a decision for reorganization of step for time-splitting.
Priority: High
Principal Investigator : Jerome Chanut (jchanut@…)
Number of weeks : 4 (TBC)

MERCATOR.9 — Improvement of OBC

Motivation: need to discuss with OBCs' experts of the consortium to organize the work; merge OBC and BDY
Status :
main tasks :
Principal Investigator : Jerome Chanut (jchanut@…)
Priority: High
Number of weeks : 3 (TBC)
