Yes, for a global attribute (or a group attribute for netCDF-4 data)
use NF90_GLOBAL as the variable ID.

The Fortran-90 interface uses overloading, so the single function
nf90_put_att serves the purpose of multiple functions with different
parameter types. If you call it with a character string value, it will
create an attribute that is a one-dimensional array of NF90_CHAR type.
If you call it with a double precision value, it creates an attribute of
type NF90_DOUBLE.
