38 | !! ** Purpose : Create the NetCDF file(s) which contain(s) all the |
---|
39 | !! ocean domain informations (mesh and mask arrays). This (these) |
---|
40 | !! file(s) is (are) used for visualisation (SAXO software) and |

41 | !! diagnostic computation. |
---|
42 | !! |
---|
43 | !! ** Method : Write in a file all the arrays generated in routines |
---|
44 | !! crsini for meshes and mask. In three separate files: |
---|
45 | !! domain size, horizontal grid-point position, |
---|
46 | !! masks, depth and vertical scale factors |
