Fabio,
A little more clarification is needed to my last reply. I said:
Each variable in the file cannot exceed 4GB (not 2GB), in netCDF
versions after 3.6.1, including the current netCDF 4.1.1. The actual
maximum size of a variable on a 32-bit platform is (2^32 - 4) bytes.
Part of the confusion is a documentation error here:
http://www.unidata.ucar.edu/software/netcdf/docs/netcdf.html#Classic-Limitations
which I just discovered hasn't been updated since the size limit on a
single variable was changed from 2GB (2^31 - 4) to 4GB (2^32 - 4) in
versions since netCDF 3.6.1.
I was confused and the original documentation is correct. The netCDF classic
format limits all but the last variable to 2GB in size. It is the 64-bit offset
file format that permits all variables to be 4GB in size, and the last variable
to be even larger. The netCDF-4/HDF5 format variant has no 4GB limits on the
size of any variable. Sorry for the confusion!
