Hi,
I've just been working with timeseries and looked at example H.2 in the
conventions document:
http://cfconventions.org/Data/cf-conventions/cf-conventions-1.7/cf-conventions.html#example-h.2
The example isn't valid because
a) the name_strlen dimension is used but not declared
b) humidity has time/UNLIMITED as second dimension, while UNLIMITED
dimensions must be first. Either it must be humidity(o,i) or time should
not be UNLIMIED.
(and c) the Conventions attribute is missing). I attach a working
example with humidity(o,i).
Trac seems to be down, so I post it here. I hope somebody can fix the
document.
Best wishes,
Heiko
