total weeks :
3+6+3+6+4+4+4 = 29 wk... 40 for man/year !

C.1 — ECUME bulk formulae (end)

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 nemo3.2_beta ok (done in 2009)
main task: (3 wk) documentation + NVTK - v3.3
Principal Investigator : Gilles Garric (ggarric@…)

C.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 - v3.3
Principal Investigator : Guillaume Reffray (greffray@…)

C.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 - v3.3
Principal Investigator : stephane LAW CHUNE (slaw@…)

C.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) - v3.3
Principal Investigator : Jerome Chanut (jchanut@…)

C.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@…)

C.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@…)

C.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@…)
