Dear CF Community,
Last summer, my counterpart Jonathan Wrotny proposed a new standard name
to capture the geopotential
height of a volcanic ash cloud top. The standard name that was settled
upon is geopotential_height_at_volcanic_ash_cloud_top.
The dimension that was proposed is the meter.
Hello:
My group is producing a climate data record (CDR) of satellite-based cloud
property retrievals in support of the NOAA CDR program. When we do our
retrievals, we do not directly retrieve parameters at cloud top but rather at
some depth within the cloud where the infrared radiation is
Kris,
Also, height of what?

Hi.
It seems to me that tacking on a description of the datum in the standard name
isn’t a good plan. It creates a linkage between standard names and grid
mappings / WKT blocks. The nature of the height of the sea surface is
not altered by the choice of datum. The values will be different,
Yes I do need a standard name for the height because, from what I understand,
all NOAA climate data records need a standard name. We produce height,
pressure, and air temperature at this cloud radiative center level. One cannot
easily translate between height and pressure without ancillary
Karl,
My point is that putting the reference surface in the standard name
(potentially) proliferates standard names for things that (like temperatures in
different units) are not different except for their reference frame. I agree
that we don’t want to put the datum information in the units,
Based on existing values of similar standard names,
*Existing*:
*height_at_cloud_top* (m)
*air_pressure_at_cloud_top* (Pa)
*air_temperature_at_cloud_top* (K)
*What about:*
height_at_cloud_radiative_center (km)
air_pressure_at_cloud_radiative_center (hPa)
air_temperature_at_cloud_radiative_center
