=== '''MERCATOR.1 — PPM advection scheme '''  ===
   '''Motivation:''' Add another scheme for tracers advection: horizontal part. Vertical part will be made by NOCL. [[BR]]

=== '''MERCATOR.2 — resolving the 2 versions of time-stepping'''   === 
   '''Motivation:''' Tracer conservation and time splitting. reference: Shchepetkin, A. F., and J. C. McWilliams, 2005 [[BR]]
   '''Status :'''Running in NEATL36 at Mercator. [[BR]]
   '''main tasks :''' Main idea:replace Leapfrog scheme by  a Fb tamporal scheme, but keep actual method for updating ssh at 3D time-stepping.  [[BR]]  
   '''workplan:''' [[BR]] 
   '''1.'''test some eventual problem of divergence of SSh in barotropic mode compared to SSH in 3d mode ( cf  Hallberg and Adcroft, OM 2009: Reconciling estimates of the free surface height in Lagrangian vertical coordinate ocean models with mode-split time stepping). [[BR]]
   '''2.'''implementation in NEMO_3.3 of this time-splitting. [[BR]] 
   '''3.'''test in high-resolution configuration at Mercator.[[BR]]
   '''4.'''take a decision for reorganization of step for time-splitting.[[BR]]

=== '''MERCATOR.4 —  Solar flux filtering at daily frequency to force biogeochemistry model. '''   === 
   '''Motivation: '''For coupled model ( physic + bio ): physic needs 24 hours (+ diurnal cycle)  or 3 hours solar fluxes, but bio need a 24 hours mean.  [[BR]]
