I'm sorry, I have to apologize. I have now discovered that what I
thought was installed as the NetCDF4 version of
ncdump must actually be an HDF4 version. The real NetCDF4 version
works just fine on this file.
I was sure I had installed it to my /usr/local/bin directory but
apparently not, or perhaps it was overwritten.
So excuse me while I wipe the egg off my face. I hope you didn't
spend too much time on this.
Meanwhile thanks for pointing out the '-k' option which I had not
been aware of.

I'm having trouble duplicating the error you are seeing. In
particular, I can't seem
to make ncdump from netCDF4 produce the message "ncopen failed" on
any file, real or imaginary,
and it works OK on 64-bit-offset files. Just to be sure, can you
please send me output from the
following, using the netCDF4 ncdump
ls -l e4oper.fc.ml.19970116-19970120.nc
ncdump -k e4oper.fc.ml.19970116-19970120.nc
The last command will say "-V" is an illegal option, but will then
print out the version number,
which is what I want to see. Ans just to be sure I understand how
the file was created, did you
use the netCDF-4.0-beta1 library to create the 7.7Gbyte file, or
did you use netCDF-3.6.2 and the
64BIT_OFFSET creation mode?
