xdfopen, missing longitude dimension

[Michael Sigmond]

Hello,
I'm trying to xdfopen a netcdf file that contains zonal-mean data. The
problem is that the file does not contain the longitude dimension. Details
below and suggestions are very welcome,
thanks,
Michael

ncdump -h test.nc:

netcdf test {
dimensions:
        time = UNLIMITED ; // (552 currently)
        plev = 31 ;
        lat = 96 ;
variables:
        float lat(lat) ;
                lat:standard_name = "latitude" ;
                lat:axis = "Y" ;
                lat:units = "degrees_north" ;
                lat:long_name = "Latitude" ;
                lat:typeConversion_op_ncl = "double converted to float" ;
        float plev(plev) ;
                plev:long_name = "Pressure" ;

                plev:positive = "down" ;
                plev:axis = "Z" ;
