Changing default NetCDF format to CDF5
Browse files Browse the repository at this point in the history 
Changing the default NetCDF file format from CDF2 (64bit_offset)
to CDF5 (64bit_data).

The CDF5 format gets rid of limitations (for all practical
purposes) on NetCDF variable size imposed by the older CDF2
file format. Also note that all E3SM run scripts already
explicitly set the NetCDF file format to CDF5/64bit_data for all
production runs.
