Hi Carol,

Yes, exactly.

re:

Very good.

re:

The default size for an IMGCOPY is 640x480.  If you want to copy the
entire file, you need to add the SIZE= keyword to your IMGCOPY command.
I'd use SIZE=SAME or SIZE=ALL.

re:

I don't understand the failure of 'ncdump'.  In order to check
it out I'd need either a copy of the netCDF file that was created
or a copy of the original METEOSAT 11 image so I could create
a netCDF file myself.

re:
> Any thoughts about how I might be doing this conversion incorrectly?

The small output seems obvious to me as I noted above.  The 'ncdump'
failure is totally unexpected.

Cheers,

Tom
