[cf-pointobsconvention] Draft 2

[Parton, GA (Graham)]

Would "sounding" be a useful alternative?

I and other atmospheric scientists use this when talking about data
taken to profile the atmosphere, either by a static instrument, e.g a
wind profiler, where you have regular vertical gridded data or data from
an ascending(descending) instrument e.g. a radiosonde, where the
vertical coordinate will not nec be regular and the observations point
is moving horizontally too.

I think "profile" is fine.  It's meaning is understood within
Oceanography and would be O.K. for irregular vertical axes.
My intention was to introduce terminology used within the community, not
to offer "string" as as a better generic name.
