Hello all,

I'm trying to replicate in TDS 5.0.0 some functionality I had working with
TDS 4.6 -- producing a collection/aggregation of NCEP GFS model output
(GRIB2 format) and exposing it via WMS.

I've been able to successfully generate the "Full Collection Dataset"
resource and it's working great (see config snippet below), but with one
exception:  the u & v components of wind are not being combined into a
unified "wind" variable, i.e., a single WMS layer that will allow the u/v
wind field to be rendered with ncWMS using barb/vector styles.

This functionality was working in TDS 4.6 without any additional
configuration, but does not seem to be working the same with TDS 5.0.

Are there specific settings I should be using in catalog.xml to tell TDS
5.0 that the "u/v component of wind" variables represent a vector field?

FYI, I'm using the TDS 5.0.0 snapshot from 2017-02-21T21:22:48.

Thanks,
Jason
