43 | !! ** Purpose : Create the NetCDF file(s) which contain(s) all the |
---|
44 | !! ocean domain informations (mesh and mask arrays). This (these) |
---|
45 | !! file(s) is (are) used for visualisation (SAXO software) and |
---|
46 | !! diagnostic computation. |
---|
47 | !! |
---|
48 | !! ** Method : Write in a file all the arrays generated in routines |
---|
49 | !! domhgr, domzgr, and dommsk. Note: the file contain depends on |
---|
50 | !! the vertical coord. used (z-coord, partial steps, s-coord) |

53 | !! = 0 : 'mesh_hgr.nc', 'mesh_zgr.nc' and |
---|
54 | !! 'mask.nc' files |
---|
55 | !! For huge size domain, use option 2 or 3 depending on your |
---|
56 | !! vertical coordinate. |
---|
57 | !! |
---|
58 | !! if nmsh <= 3: write full 3D arrays for e3[tuvw] and gdep[tuvw] |
---|
59 | !! if 3 < nmsh <= 6: write full 3D arrays for e3[tuvw] and 2D arrays |
---|
60 | !! corresponding to the depth of the bottom t- and w-points |
---|
61 | !! if 6 < nmsh <= 9: write 2D arrays corresponding to the depth and the |
---|
62 | !! thickness (e3[tw]_ps) of the bottom points |
