We are pleased to announce the first release of the NEMO Configuration Manager.

This software called SIREN, allows you to set up regional configuration of NEMO.\\
The software is written in FORTRAN95 and available in the NEMOGCM/TOOLS directory of nemo_v3_6_STABLE (since r6468).

SIREN allows you to create your own regional configuration embedded in a wider one.\\
Actually SIREN is a set of programs to create the input files you need to run a NEMO regional configuration.
* '''create_coord.f90''' to create regional grid coordinates (refined from an ORCA grid).\\
  Note: for now SIREN can not work too close from North pole.
* '''create_bathy.f90''' to create regional grid bathymetry (extracted or refined from wider one).
* '''merge_bathy.f90''' to merge regional grid bathymetry with wider grid bathymetry at boundaries.
* '''create_restart.f90''' to create initial state file from coarse grid restart or standard outputs.
* '''create_boundary.F90''' to create boundaries conditions from wider configurations output fields.

As demonstrator for a first start, a set of GLORYS files (global reanalysis on ORCA025 grid), as well as examples of namelists are available [http://prodn.idris.fr/thredds/catalog/ipsl_public/rron463/catalog.html?dataset=DatasetScanipsl_public/rron463/INPUT_SIREN.tar here]

SIREN documentation is available [/doxygen here]. In this documentation you could find a quick start guide to help you to start with SIREN.

A summary of the NEMO community’s feedbacks on this first release of the Configuration Manager will be discussed during next !Developers Committee, 28 June. It would be of great help for us to get your comments and feedbacks of your first tries before this date.\\
