Jonathan,
Yes, I think your answer before is the answer now, but I'm just clear

:standard_name = "sea_surface_height_above_reference_datum";
:grid_mapping = "Albers_Projection
This question certainly pops up on a regular basis.
After a discussion on the MMI 'Ask' metadata discussion list, OceanSITES
decided to add 2 attributes to the Z axis variable, one is 'reference',
which
is intended for human readers, and the other is

main problem is getting a sufficient understanding
CF folks,
On a telecon yesterday with a coastal inundation modeling group, one
of the PIs asked me how to handle vertical datums in NetCDF --
specifically where to specify that the model bathymetry and water
levels were were relative to NAVD88. I wasn't sure how to reply.
Was there any resoluti
