Bryan, I'm sorry if I missed or forgot something from the early part of
the discussion, but I'm utterly mystified. What does THREDDS have to do
with anything?
Being part of several collective experiments that could be thought of
dealing with ensembles, I'm having a hard time espousing an ensemble
axis.
Is the ensemble axis static? (i.e not UNLIMITED)? What happens if I want
to increase the size of an ensemble later? (We recently added 2 members
to a 3-member initial-condition ensemble we've submitted to IPCC AR4).
For the kinds of ensembles we have in mind, can we stay within the file
size limits?
The only thing I can think of to which THREDDS is even remotely relevant
is my general comment based on some use cases, that an "ensemble
dataset" is probably not contained in one file. But that's a very
general observation, that we no longer think of a dataset as mapping on
to a file, and that aggregation is a fact of life. Long time series is
my chosen example of aggregations we all routinely do.
I certainly wasn't meaning to suggest, or even imply, any software
choices or aggregation methods to go along with this. This is a comment
about metadata only.
Thanks,
