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 revision 6468).
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.

As demonstrator for a first start, a set of GLORYS files (global reanalysis on ORCA025 grid), as well as examples of namelists are available here.

SIREN documentation: here.
Forum : Pease post your questions or comments regarding the use of SIREN in the NEMO configuration manager forum here.

Others Pre-processing utilities

AGRIF nesting tool:

How to create the grid coordinates, the surface forcing and the initial conditions required by each child model.

Data interpolation with cdo:

The aim is to remap from/to a regular geographic grid to/from an other curvilinear grid, especially the ORCA one. see here.

Data compression:

for netdcf files: example for COREII forcing files.

Weight creation for online interpolation :

see here and here.


OPABAT is a group of Fortran and IDL routines which allows to build a bathymetry on the grid of the dynamical oceanic part, OPA.

Data interpolation:

The aim is to remap from a regular geographic grid to an other curvilinear grid, especially the ORCA one. It will be provide by SOSIE

Setting up MPP configuration tool:

This Fortran based tool provides to the user information to choose the best domain decomposition. The proposed solution will be the one with an optimized number of processos in suppressing eventual useless land processors.

Conversion of restart files

This Fortran based tool performs light changes on restart files (NetCDF or DIMG format) to ensure their compatibility with the new IOM package in the standard version of NEMO i.e. since the tag nemo_v2 and later:
Chge_Rst_files.tar 80.00 kB

ORCA grids generator

This Fortran based tool allows to generate an ORCA grid type: gridgen_CECILL.tar 290.00 kB
