[netCDF #XET-647811]: About return value of nf_open in fortran

Hello,

ier contains an error code; it should be NC_NOERR, or 0, if the file was opened 
successfully.  If the file was opened successfully, we would expect the ncid to 
be non-zero.  It appears that there was an error opening the file.  The netCDF 
API returns negative values for errors, and has no error defined for a value of 
`2`, so it appears that this is a filesystem error.  Are you certain you have 
permission to read the file, and that the file exists?
