july 2009 NEMO User meeting 2009 and 2010 evolution #1- “shared” = daily support to users, web paper documentation, model user interface. #2- “sustainable” = inscribed in a long term perspective: well thought architecture and interfaces #3- “state-of-the-art”= development/implementation of upgraded physics and numeric #0- “specific action”= priority development for the current year Planned Objectives 2009: 1/2 #0 O/I/A environment (“coupled ready”) generic coupling interface (achievement) documented ORCA2-LIM and its physics based on NEMO (IsENES) #1 user friendly (“shared”) IOM - for output (first implementation) Configuration manager (2 years, start in mid 2009) (My_Ocean) TOP LIM3 paper and web documentation (2009) reference configurations (continuation) #2 developer friendly (“sustainable”) suppression of rigid-lid option rewriting of mpp library + timing VVL + improved time stepping Planned Objectives 2009: 2/2 #3 new features (“state-of-the-art”) #3.1 - implementation of development (coming from outside NEMO team) Numerous physical package for climate ocean model (Tidal mixing, light penetration + ocean colour, diurnal cycle, ice-self param., katabatic winds) conservative leap-frog/Asselin filter observation operator (NEMOvar consortium) #3.2 - short-term developments (from the consortium members, end in 2009) New forcing (tidal potential, atmos. pressure, new river input scheme) embedded sea-ice mass/heat/salt fluxes lateral physics (iso-neutral operator, skew flux... etc.) vertical physics (improvement of existing (tke2), addition of new one: GLS) sea-ice improvements (momentum forcing, snow-ice formation, EVP on LIM2) #3.3 - long-term developments (from the consortium members, will continue in 2010) assessment of s-coordinate split-explicit + variable volume (stability conservation) generalisation of the split-explicit free surface (merge flt-ts, optimisation) AGRIF with sea-ice (from simple to fully AGRIFed)
