104	Sigma coordinate
105	Hybrid coordinate
106	Depth below land surface (m)
107	Potential temperature (theta) (K)
108	Pressure deviation from ground to level (Pa)
109	Potential vorticity (K m2 kg-1 s-1)
110	Geometrical height (m)
111	Eta coordinate
112	Geopotential height (gpm)
113	Logarithmic hybrid coordinate
160	Depth below sea level (m)
255	Missing

Notes:

( 1) Negative values associated to this coordinate will indicate depth below ground surface. If values are all below surface, use of entry 106 is recommended, with positive coordinate values instead.

( 2) The Eta vertical coordinate system involves normalizing the pressure at some point on a specific level by the mean sea level pressure at that point.
