the netCDF file. Probably you are both already doing that, but I wa

Hello
The discussion on CF-1.6 DSG clarification: time series & lat/lon coordinates
provides us with further example of the use of scalar coordinates and their
potential interpretation. I would like to use this to investigate the question
of scalar interpretation.
The conversation on this iss
tureType provides, though.

Hi John:
1) The coordinates attribute is not new to DSG, it has been around since
the beginning of CF. This defines the "auxiliary coordinate variables",
that is, coordinate variables that do not follow "lat(lat)" template. I
think it would be good if Grads et al could be upgraded to use them.
Hi all,
We ran into a glitch after converting one of our buoys to the new CF-1.6
discrete sampling geometries (DSG) format, and I'm looking for advice. This
dataset uses the single time series format, like the one provided in the
template of the CF document in Example H.4:
