Hi all,
For what it's worth, I can open this file without problem. I'm using:
> Config: v2.2.1.oga.1 little-endian readline grib2 netcdf hdf4-sds hdf5
> opendap-grids,stn athena geotiff shapefile
on a Mac. My .netrc contains the same information as below (different
username/password of course). My .dodsrc file is also similar, but I
think you need to remove the leading hash, and I use a leading dot
(.netcdf and .dodsrc) in place of underscore (_netrc and _dodsrc)
