[IDV #SJQ-840722]: .idx files

Greetings Rob,

It looks like you can directly load in the grib data without using the ctl or 
idx files. That said, I would recommend that you access the data via the NOMADS 
THREDDS server. Simply use this URL in the "Data Choosers -> Catalogs" screen 
in the IDV Dashboard:

http://nomads.ncdc.noaa.gov/thredds/catalog.xml

In particular, I think you are looking for the following area in their THREDDS 
archive:

http://nomads.ncdc.noaa.gov/thredds/catalog/ruc/catalog.xml

Let me know if this gets you what you need :-)

Cheers!

Sean
