Hi everyone,
I'm stumped: any ideas why the following regular gridded FMRC dataset
produces an empty WCS capabilities document (no variables/coverages get
listed; ContentMetadata section is entirely missing)?:

http://oos.soest.hawaii.edu/thredds/catalog/hioos/roms_forec_regridded/hiig/catalog.html

In particular, I'm looking at the Best Time Series at:

http://oos.soest.hawaii.edu/thredds/catalog/hioos/roms_forec_regridded/hiig/catalog.html?dataset=roms_hiig_forecast_regridded/ROMS_Hawaii_Regional_Ocean_Model_Regridded_best.ncd

Whose WCS URL is this:

http://oos.soest.hawaii.edu/thredds/wcs/hioos/roms_forec_regridded/hiig/ROMS_Hawaii_Regional_Ocean_Model_Regridded_best.ncd?service=WCS&version=1.0.0&request=GetCapabilities

The other services all work fine, including OPeNDAP, NCSS, WMS, ISO, and
NcML.

Although the original ROMS ocean forecast model was on a curvilinear grid
(which WCS cannot handle), we've regridded onto a regular grid. One
positive outcome of this was that I should be able to turn on WCS for it
now (so that people can download GeoTIFFs); however, I'm not having any
luck yet. The logs are not showing anything useful. threddsServlet.log just
shows this:

I have other regular gridded FMRC's whose WCS works fine; one example
(NCOM):

http://oos.soest.hawaii.edu/thredds/catalog/pacioos/ncom/hawaii/catalog.html
http://oos.soest.hawaii.edu/thredds/catalog/pacioos/ncom/hawaii/catalog.html?dataset=ncom_hawaii/NCOM_Hawaii_Regional_Ocean_Model_best.ncd
http://oos.soest.hawaii.edu/thredds/wcs/pacioos/ncom/hawaii/NCOM_Hawaii_Regional_Ocean_Model_best.ncd?service=WCS&version=1.0.0&request=GetCapabilities

In case it helps, I've placed my catalog file and one of the data files
(174 MB) on anonymous FTP:

ftp ftp.soest.hawaii.edu
cd jmaurer
get ocn_mod_hiig.xml
get hiig_forec_gridded_20120402.nc

Thanks for your help on this!,
