The current NUWG convention documents are all in

    ftp://ftp.unidata.ucar.edu/pub/netcdf/Conventions/NUWG/

and they all specify using "_FillValue".  This is the only attribute that
the netCDF library will recognize and treat specially, by using it to
override the default fill values when prefilling data because of writes out
of sequential order.

There are other non-NUWG developers who have published other conventions in
the Conventions directory that you might want to look at as well.
