The usual practice in netCDF to describe position along a dimension is
to create a variable that varies in that dimension and has the same
name as that dimension. Variables that satisfy these conditions are
called coordinate variables.

Thus in your case

xvarid=ncdf_vardef(data, 'west_east', xid, /float)
yvarid=ncdf_vardef(data, 'south_north', xid, /float)

and then put your coordinate data into those variables.

I must say that 'west_east' and 'north_south' are unusual names for
variables. Personally, I would be inclined to call them "x" and "y"
and give each one a long_name attribute that describes it in more
detail.
