FYI, I finally submitted a proposed convention for point obs data to the CF 
group:

feedback to http://cf-pcmdi.llnl.gov/trac/ticket/37 would be welcome.

#37: Conventions for Point Observation Data
----------------------------+-----------------------------------------------
Reporter:  caron           |       Owner:  cf-conventions@xxxxxxxxxxxxxx

== 1. Title ==

Conventions for Point Observation Data

== 2. Moderator ==

TBD

== 3. Requirement ==

Current conventions are oriented towards gridded data. This proposal
extends the framework to specify how to encode "point observation" data.

== 4. Initial Statement of Technical Proposal ==

We show six types of point observational data, and describe a general way
to encode many variations. The main technical extension is a simple way to
describe ragged arrays, for the case when rectangular arrays are too
inefficient.

== 5. Benefits ==

* Many data providers would like to use CF conventions when storing their
observational data.

* This will allow a standard for converting things like BUFR data into
netCDF.

== 6. Status Quo ==

Currently sections 5.4 and 5.5 describe 2 examples of point observations
(station time series and trajectories). This proposal generalizes those.

== 7. Detailed Proposal ==

Because of the length of this, I have created a
[http://www.unidata.ucar.edu/software/netcdf-java/CDM/CFpoints.html
seperate web page] to make it easy (for me) to edit. I can reformat later
when it is close to being finished, or if others need to edit it.
