MERCATOR.1 — Finalisation of 2009 actions

Motivation: Eigth actions of the 2009 work plan have been implemented and validated. They need to be phased with the last version of NEMO, checked with NVTK, and incorporated to the trunk together with the documentation.
main tasks : (15 wk)
(1) Atmospheric pressure (2 wk) phasing with V3.2, NVTK and doc - v3.3
(2) Tidal potential : (4 wk) merge with Met Office Open boundary condition, NVTK and doc - v3.3
(3) Improvement of OBC (1 wk) doc - v3.3
(4) PPM advection scheme (1 wk) NVTK and doc - v3.3
(5) EVP rheology in LIM2 (2 wk) NVTK and doc - v3.3
(6) On-the-fly interpolation for the initial state (3 wk) cleaning, NVTK and doc - v3.3
(7) On-line diagnostics (2 wk) cleaning, NVTK and doc - v3.3
Principal Investigator : Clement Bricaud (cbricaud@…)

MERCATOR.2 — GLS Vertical scheme (end)

Motivation: Mellor Yamada 2,5, generic length scale (Umlauf and burchard 2003) +boundary conditions(Craig and Banner)
Status : Running on NEMO_2.3; development on NEMO_3.2
main tasks : (6wk) Phasing, NVTK and doc - v3.4
Principal Investigator : Guillaume Reffray (greffray@…)
Deadline :3rd September 2010 Priority: High
Science Reviewer : Chris Harris (TBC)
System Reviewer : Rachid Benshila (TBC)

MERCATOR.3 — 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 : OK for NEMO 2.3
main tasks : (3 wk) Phasing, NVTK and doc - v3.4
Principal Investigator : stephane LAW CHUNE (slaw@…)

MERCATOR.4 — resolving the 2 versions of time-stepping

Motivation: Tracer conservation and time splitting. reference: Shchepetkin, A. F., and J. C. McWilliams?, 2005
Status :NVTK OK. commit early 2010
main tasks : (6 wk) Documentation and phasing (see A.1) - v3.4
Principal Investigator : Jerome Chanut (jchanut@…)

MERCATOR.5 — 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 ....
Status :Ready. Need to iterate with Gurvan with respect to recent implementation of explicit bottom friction. comit: Mid 2010
main tasks : (4wk) phasing, NVTK and doc- v3.4
Principal Investigator : Jerome Chanut (jchanut@…)

MERCATOR.6 — Logarithmic bottom friction

Motivation:Add Logarithmic bottom friction for tidal applications
Status : Development OK. comit: Mid 2010.
main tasks : (4 wk) phasing, NVTK and doc - v3.4
Principal Investigator : Jerome Chanut (jchanut@…)

MERCATOR.7 — Simple solar penetration scheme using KPAR

Motivation: Introduce a two bands solar attenuation scheme (Rochford et al, JGR 2001), simpler and cheaper than 4 bands one. The scheme uses climatological KPAR attenuation coefficient in order to take into account the spatial variation of the light penetration in the ocean.
Status :Development OK. comit: Mid 2010
main tasks : (4 wk) phasing, NVTK and doc - v3.4
Principal Investigator : Jerome Chanut (jchanut@…)

MERCATOR.8 — 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 : (2 wk) documentation + NVTK - v3.4
Principal Investigator : Gilles Garric (ggarric@…)
