Daryl, I just went and looked up the dataset you referenced: http://thredds.ucar.edu/thredds/catalog/grib/NCEP/RAP/CONUS_13km/catalog.html and didn't have any trouble pulling down data. It's possible you were having trouble hitting the motherlode:port url, since we were having server issues this week. Try the above and let me know if you're having problems. Also, how did you generate the url in the support e-mail you sent? It does indeed generate a 404, but I couldn't recreate it here. -Lansing > Hi Lansing, > > Thanks for the suggestion.
