Try handing Ferret the unconstrained dataset URL (i.e., without the "?v[...]")
and then selecting and subsetting a variable through Ferret. Ferret should be
able to construct and request the correct subset (using a URL similar to the
one you list above). I'm not that familiar with Ferret or how to subset a
dataset but here's the result of a quick google on "ferret opendap":
which has a link to
which looked useful.
Hope that helps,
