Hello Remik,

Are you mostly interested in working with very large files?

The next release of netCDF, version 3.6, will be released shortly, and
introduces a new data format, 64-bit offset mode, which allows the
creation of very large files, although there are still some size
restrictions.

Version 3.6, which introduces the 64-bit offset format, is still
several versions away from NetCDF 4.0, which will allow a third
format, HDF5, to be accessed with the netCDF interface. This will also
allow multiple unlimited dimensions, as well as some other new
features.

If you are primarily interested in creating large files with netCDF,
then you should try version 3.6.0, which is available in beta on the
ftp site, and pass the new flag NC_64BIT_OFFSET to the nc_open cmode
parameter.

If you have any questions, please let me know.

Thanks,
