GRIB:
Height is a measure of vertical distance. "Sea surface height" is a time-varying quantity. The "geopotential datum" is the geopotential reference level (level of zero geopotential) where this is not a specifically named level such as the geoid or a reference ellipsoid.

"Height_above_X" means the vertical distance above the named surface X. The "geopotential datum" is the geopotential reference level (level of zero geopotential) where this is not a specifically named level such as the geoid or a reference ellipsoid. "Sea surface height" is a time-varying quantity.

GRIB:
"Height_above_X" means the vertical distance above the named surface X. "Sea surface height" is a time-varying quantity. The "geopotential datum" is any estimated surface of constant geopotential used as a datum i.e. a reference level; for the geoid as a datum, specific standard names are available. To specify which geoid or geopotential datum is being used as a reference level, a grid_mapping variable should be attached to the data variable as described in Chapter 5.6 of the CF Convention.
