This might have worked if you had closed the file with NF_CLOSE after
creating it with NF_CREATE, but that's probably not what you intended.
You should usually use either NF_CREATE or NF_OPEN, not both.
NF_CREATE is intended for when you want to create a new netCDF file,
and NF_OPEN is intended for when you want to open an existing netCDF
file that was previously created.

For an example of the sequence of calls used to create a netCDF
dataset, see "4.1 Creating a NetCDF Dataset" in the Fortran User's
Guide: 

  http://www.unidata.ucar.edu/packages/netcdf/guidef/guidef-9.html#HEADING9-0

For examples of opening an existing netCDF dataset, see the subsequent
sections "4.2 Reading a NetCDF Dataset with Known Names" and "4.3
Reading a netCDF Dataset with Unknown Names".

Also, feel free to direct questions like this to
"address@hidden" rather than the mailing list
"address@hidden".  Despite the somewhat misleading name,
the latter is actually a mailing list of netCDF users.
