Re: NCL and unipost

Hi Scott,
Can you upload a one of these grib files using the instructions found at
http://www.ncl.ucar.edu/report_bug.shtml ?
Please let me know (off-line) the name of the file.
Thanks,
 -dave

FYI - this should really be posted to ncl-talk rather than ncarg-talk. it is an NCL question.
