Re: A Quick Question of NCL (ncl_convert2nc), Thanks!

I am not sure what the problem is.

We can do an 'ncl-filedump', 'ncl_convert2nc' and open
the file in a regular NCL script. We have done this
on a MAC and on several linux OSs. I am attaching
a gzip'd dump of the file.

If you downloaded the file via ftp and, inadvertently, used
'ascii' mode then you would get bogus characters.
