Chris,
See http://nco.sf.net#help for NCO issues.
The -X option behaves well with unstructured grid coordinates
formatted in the CF-ish way NCO expects. It is agnostic about UGRID.
Please move this thread to the site above
if it does not work for you on a UGRID dataset.

I suggest you store it as Dave Allured says, with dimensions
(time, ID). This is often called an "unstructured grid".
NCO has no problem subsetting data on unstructured grids,
where lon(ID) and lat(ID) are known as auxiliary coordinate
variables.
Good to know. I just took a look at the NCO docs, and it's not totally
clear to me if it will "just work" with a file that conforms to the
UGRID standard:
http://ugrid-conventions.github.io/ugrid-conventions/
will it?
-CHB
Just use
ncks -X lon_min,lon_max,lat_min,lat_max -X ....
It's all in the manual, which has an index that points to
examples of using unstructured grids and their proper CF
formatting.
