[[BR]] ''' Status :''' Preliminary version available in Sept 2013. Fortran routines only.[[BR]] ''' Main tasks :''' Develop tools (scripts, Fortran routines, graphical interfaces) to create inputs needed to run a new configuration. Take into account online (AGRIF) or offline nesting. Tasks scheduled in 2014: Debug, Enable creating a configuration around the North Pole, ensure compatibility with existing nesting tools interface. Possible future developments in 2015 and beyond: Vertical remapping (or should it be online ?), Python scripts (?), graphical interface (?)

Dupont (Env. Canada) has been reported in tickets 106 and 107. [[BR]] ''' Main tasks :''' This would be done in two steps, spanning two development years: 1. First, implement basic coupling of the barotropic mode at the baroclinic step level (Similar to what has been done by Penven et al. (2006) in ROMS). 1. Second, implement full coupling at the barotropic time step level (Debreu et al., 2012) In any case, try to ensure volume conservation (relying on the forward nature of barotropic equations with time splitting).

See what happens in global eddying simulations.[[BR]] ''' Status : ''' Not started yet. [[BR]] ''' Main tasks :''' Changes are far less computationally expensive than turning to the full non-hydrostatic equations. These would however be significant. Quoting Marshall et al. (1997): "the quasi-hydrostatic model retains cos(latitude) Coriolis terms in the zonal and vertical momentum equations, neglects Dw/Dt in the vertical and does not make the shallow atmosphere approximation".[[BR]] ''' Science Reviewer:''' TBD (Gurvan ?)[[BR]] ''' System Reviewer: ''' TBD [[BR]] ''' Deadline: ''' 2015[[BR]] ''' Priority: ''' Low [[BR]] ''' Depends on:''' resources available after completion of tasks above[[BR]] ''' Principal Investigator : ''' Jérôme Chanut
