It is a true NetCDF4 file, but I'm surprised at what you say. I used to
read the exact same file with PyNIO before I switched over to a 64-bit
Linux system and recompiled NCL and PyNIO. In fact, now my old code,
where I used Nio for reading, is causing python to crash with messages
such as 'ncdiminq: ncid 65536: NetCDF: Invalid dimension ID or name'.
But the same code, for reading the same file, used to work, I think
(unless I switched the file format at some point, but I don't remember
doing that). Could you have a look at the following file:

ftp.phys.uu.nl/uploads/DailyColDens.th.2002.nc4

and tell me whether PyNIO is supposed to be able to read it?

Thanks,
