Last edited Timestamp?
Substream 3.1 : new features from the community
Description and participants
- Tidal mixing (Bessière 2007, Koch-Larrouy 2008, Koch-Larrouy et al 2008a,b,c)
- 3 bands light penetration + ocean colour (Lengaigne et al CD07, GRL08)
- Diurnal cycle on solar radiation (Bernie et al. 2007)
- Ice-shelf melting parameterisation (Wang & Beckmann AG07, PhD of P. Mathiot)
- Parameterisation of katabatic winds (PhD of P. Mathiot)
- Conservative Leap-Frog + Asselin filter (Leclair & Madec OM08)
- Observations operator code and increments application

Substream 3.2 : short-term developments of new features by the consortium members
Description and participants
- New forcing (Tidal potential, atmospheric pressure) and river input scheme (continuation & end)
- Embedding sea-ice inside the ocean (continuation & end)
- Revisit of mass and salt fluxes between ice, ocean and air (continuation & end)
- New advection schemes (PPM, Quickest and Prather)
- Lateral ocean physics (isoneutral operator, skew flux, Visbeck coefficients, slope limitation, Aiki formulation) (continuation & end)
- Ice improvements (momentum forcing, snow-ice formation, EVP rheology in LIM2)
- Improved s-coordinate option (hydrostatic pressure gradient computation, POLCOM-style s-coordinate) (continuation & end)
- Vertical physics: improvements of TKE scheme, addition of a Generic length scale model
Advancement
Substream 3.3 : long-term developments of new features by the consortium members
Description and participants
- Revisit of the time stepping in TOP (2 years, start in 2009)
- Split-explicit + vvl conservative scheme (2 years, started in 2008)
- Inclusion of the effect of waves in the marginal ice zone (2 years, start in 2009)
- Toward a generalisation of the split-explicit free surface (2 years, start in 2009)
- Interface to the OASIS 4 coupler (2-3 years, ongoing, started in 2008)
- AGRIF and sea-ice (from 0 order to LIM2 and 3 fully AGRIFed) (3 years, started in 2008)
- Development of TAM (ANR VODA), with a major contribution from the LJK team (3 years, started in 2008)
- High parallelisation on new plateforms (GPU graphic cards, OpenMP etc …, start in 2009)
