Hi Liz,
I get the same thing attempting to open via addfile from within NCL.
Do you know for certain that the host e4ftl01.cr.usgs.gov is an
OpenDap server?
Unfortunately I am unable to duplicate the ncl_filedump part -- if I
manually download the file, it can be read just fine by ncl_filedump
on yellowstone, under both NCL versions 6.1.2 and 6.2.0. What
platform are you running on?
