I wonder whether anyone strongly disagrees. In the new CF process, as the old,
consensus should be found if possible. I think Alison will sum up, as she
posted yesterday.

(1) I would omit "grid" because of consistency with cell_measures and
cell_methods, and because "grid" might imply that it is only relevant for,
say, a 2D array of cells, which might not be the case; you could use such
a variable even if there were only a single cell.

(2)

In existing CF stdnames, "height" means distance above the surface, and
"thickness" means vertical extent, so I think this measurement is a thickness.

Best wishes
