Rotated pole coordinate system

        I'm quite new to NCL and I'm exploring its capabilities.

        The output of our meteo-chem model is given in a "rotated pole"
        (RP) coordinate system (CS). This means that the "north pole" of
        the CS is located in a different location with respect to the
        geographical one. In the RP frame, the grid is regular which
        means that is non-regular in the geographycal system (GS).

        The RP CS is fairly common and is also defined in the CF
        convention for NetCDF so I expect NCL to be able to deal with
        it.

        Should I expect that a CF complianf netcdf file with RP CS be
        plotted correclty?

        Below there is the ncdup -h of a typical file

netcdf qq {
dimensions:
        lon = 110 ;
        lat = 95 ;
        time = UNLIMITED ; // (24 currently)
variables:
        double lon(lon) ;
                lon:long_name = "longitude" ;
                lon:units = "degrees_east" ;
                lon:standard_name = "longitude" ;
        double lat(lat) ;
                lat:long_name = "latitude" ;
                lat:units = "degrees_north" ;
                lat:standard_name = "latitude" ;
        char rotated_pole ;
                rotated_pole:grid_mapping_name = "rotated_latitude_longitude" ;
                rotated_pole:grid_north_pole_latitude = 36.5 ;
                rotated_pole:grid_north_pole_longitude = -170.25 ;
        double time(time) ;
                time:units = "day as %Y%m%d.%f" ;
        float CO(time, lat, lon) ;
                CO:long_name = "CO" ;
                CO:units = "g/m2" ;
                CO:grid_mapping = "rotated_pole" ;
                CO:_FillValue = -9.e+33f ;
