IFS-NEMO

Two technical details, for completeness:

NEMO uses partial cells at the bottom. On each column, the last wet cell is thinner than what the single dimensional bounds would prescribe. Basically, the deepest cell is cut at the bathymetry depth. If you want, I can also provide you with the thickness of the deepest cell (it'll be a 2D array though, and is horizontal resolution dependent).
NEMO runs with nonlinear free surface. The effective depth of the vertical levels varies at each time step, on each column, responding to sea-surface height variations. However the variations in thickness is quite small (the total variation is of the order of the meter, distributed across the full column), so assuming that the outputs are effectively at the specified depth is a reasonable assumption for most diagnostics.
