ORCA2_LIM reference runs

A - Purposes:

Document the changes from ORCA2-LIM based on OPA8.2 and ORCA2-LIM base on last NEMO version
Key changes to be documented:

# Existing one :

• partial step representation of bottom topography
• updated TKE physics (surface/internal wave breaking)
• new sea-ice component (LIM-3)

# Existing but not included in NEMO trunk :

• Kz tides including ITF specific formulation (Laurent & Ariane PhD)
• mesoscale eddy parametrisation : added in momentum equations (Aiki) (Claude/Gurvan? Japan)
• 3 band light penetration (RGB) (Sebastian Japan)
• Ocean color used to specified time-space varying light penetration (Sebastian Japan)
• Diurnal cycle on qsr (from daily mean value) (Sebastian Japan)

# Forth coming one :

• mesoscale eddy parametrisation : Griffies scheme + Visbeck coefficient (MetOffice?, NOCS)
• npc reactivation (Claude/Gurvan?)
• conservative leap-frog (Matthieu)
• vvl + conservative leap-frog (Matthieu)

B - Agenda:

C - To do list/ Remaining Questions:

• check climatological CORE bulk forcing fields computed during 1st and 2nd year
• do moficiation to perfom annual mean outputs except the last year
• check with Martin that all ice parameters for LIM 3.0 are the best one for ORCA2_LIM.

Questions to solve when setting the control simulation:

• What are we doing with runoffs ? which climatology ?
• freswater budget, annual correction ? other
• Do we take into account the ice melting of Greenland and Antarctic into runoffs directly ?
• advection scheme to use ?
