Re: [cf-pointobsconvention] Draft 2

Was there something wrong with the term 'profile'? I thought that was reasonable. Some profiles will not be regular, and I think that's OK.

Re the Z axis, it would be nice to know for sure whether the Z axis should be interpreted as 'surface'. (Other possible surfaces exist, and I suppose an abstract form of Z is also possible. So if we want determinism, we could either say "lack of characterization always means surface" or "Z must be described, if only to say it is 'surface'.")

ok. anyone with a better name is welcome to offer it. What is
"data that has an array of values along the vertical dimension"?


For oceanographic moorings we have "profile" data, such as what comes
from an Acoustic Doppler Current Profiler, and data that we call "string"
data such as what comes from a series of instruments (CTDs, Radiometers)
mounted on a vertical rope or wire beneath the buoy.

Profile data is usually stored on a regularly spaced Z-axis and string
data is stored on an irregular Z-axis as the depths are often like 1, 10,
20, 40, 60, 80, 100, 150, 200, 250, and 300 meters.
