Sorry, our TDS has been in a state of flux and the URL changed slightly yesterday afternoon. Try this link instead:

http://oos.soest.hawaii.edu/thredds/catalog/hioos/roms_forec/files/catalog.html?dataset=hioos/roms_forec/files/hiig_forec_20090828.nc

You will find the following access methods listed: OPeNDAP, HTTP, WCS, WMS, and NetCDFSubset. Thanks again for giving this a look for me!

Aloha,
John Maurer
