Does anyone have any specific examples/recommended approaches of how to
specify vertical datums in CF-Compliant NetCDF? I don't see any definitive
explanation of how to do this in any of the documentation. I also see
where people have asked this question in the past, but there never appears
to be a final recommended approach.
Specifically, I'm trying to make sure that its clear that the "z"
(bathy/topo) and "eta" (water level) are being expressed relative to
either NGVD29 or NAVD88...currently the "CF Standard Names" for
"sea_surface_height*" mention only mean water level, geoid or
ellipsoid...none of which are really the same as NGVD29/NAVD88...and the
"depth" standard name has no other variants which look appropriate.
Previous discussion on this topic include approaches of creating a new
standard names (e.g. water_surface_height_above_reference_datum), adding
a new piece of metadata (e.g. reference=NAVD88)...but none of these have
made it into the "CF standard name" document or the CF v1.x Conventions.
Is there a specific recommended approach? If not, is someone working
on this?
thx,
jrd
