We should agree on what exactly this file should contain but for now I had to start with something and here it is.
Both the Northern and Southern hemisphere domains are included in this file; with corresponding dimensions and variables being identified with the *_n and *_s suffixes, respectively.
NEMO uses the Arakawa C-grid formalism with squarish meshes. As such, the point at the very center of a given mesh is the T-point, while points that define the 4 corners of the mesh are F-points.
The exact content of current state netCDF file for the 1° resolution domain:
