  8.  creation details:
        The raw 12-month dataset from Dai&Trenberth
        (runoff2ocean-mon-fromStn-1deg-2d.bin) was converted to a flux
        in kg/s/m^2 and written to netcdf with fields required
        by the dlnd7. 
        
        Time-invariant runoff was added for Antarctica based on Large's
        value of 73000000.0 kg/s (=0.073Sv) for this continent.
