Jonathon,
Thanks for your response.
Would you, or whoever can do this, add
sea_water_pressure (canonical units dbar)
to CF standard names. Old oceanographers (like me) are more used
to pressure in units of dbar. Pa is more in keeping with the
canonical units of other pressures in CF, but bar is in udunits
so perhaps it could be dbar.
Regarding ADCP measured acoustic echo intensity, my current data
files have this as a count. There is an algorithm to convert this
to a measure of acoustic_echo_intensity in decibels (dB). Is there a
need to distinguish this from acoustic_echo_intensity in other media
by perhaps calling it sea_water_acoustic_echo_intensity?
dB is a non-SI unit and not in udunits (we have a lot these in
oceanography). I'm not sure where to go with this one.
