We decided to based our future work on the SIREN tools developed by Mercator-Ocean. '''Description of Mercator's configuration manager: SIREN : System and Interface for oceanic RElocatable Nesting''' Siren is a software used to build and launch, quickly and easily, regional oceanic simulations. These simulations are initialized and forced at boundaries by Mer- cator Ocean system. So thanks to Siren, a user can easily add some physical processes as tide, change some parameters, apply runoff as a flux, or use better bathymetry, atmospheric forcing... and of course get a higher resolution: . Siren extracts bathymetry from child les and merges it with parent bathymetry at boundaries.[[BR]] . Siren builds open boundaries condition files from parent's conguration output files.[[BR]] . Siren creates runooff files over the area, and digs bathymetry to create a canal for rivers described as a flux.[[BR]] . Siren creates a new restart le for a domain splitting from a given restart file or an output file.[[BR]] . Siren compiles and launches NEMO2.3 on Mercator Ocean cluster.[[BR]] . Siren makes some post-processings on the new conguration.[[BR]] [[BR]] === '''MERCATOR.10 — User Support''' === '''Motivation:'''Provide support to users of NEMO.[[BR]] '''Number of weeks : ''' 2 [[BR]] === '''MERCATOR.11 — Code Reviewing ''' === '''Motivation:'''Reviewing code from NEMO partners [[BR]] '''Number of weeks : ''' 4 [[BR]] === '''MERCATOR.12 — Beta Testing''' === '''Motivation:'''Beta testing of the next relaese[[BR]] '''Number of weeks : ''' 4 [[BR]] === '''MERCATOR.13 — Exchange with others centers''' === '''Motivation:'''System Team meetings, Developers Team meetings,NEMO Users meetings, partcipate to the merge party.[[BR]] '''Number of weeks : ''' 4 ''' [[BR]] '''aditionnal work:''' [[BR]] '''adaptation of PISCES to the VVL :''' compare work done by Guillaume Reffray with work done by UK Met Office.
