== A - Purposes: ==

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

# 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)

== 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.
   * use the corrected interpolated temp/ salinity fields in poles from PHC for initialization suggested by Sylvain Bouillon

Questions to solve when setting the control simulation:[[BR]]
   * 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 ?
