      <Description>A spherical harmonic model of the magnetic field of Jupiter is obtained from vector magnetic 
        field observations acquired by the Juno spacecraft during its first nine polar orbits about the planet. 
        Observations acquired during eight of these orbits provide the first truly global coverage of Jupiter's magnetic field with a 
        coarse longitudinal separation of ~45° between perijoves. The magnetic field is represented with a degree 20 spherical harmonic model 
        for the planetary (internal) field, combined with a simple model of the magnetodisc for the field (external) due to distributed 
        magnetospheric currents. Partial solution of the underdetermined inverse problem using generalized inverse techniques yields a model 
        (Juno Reference Model through Perijove 9) of the planetary magnetic field with spherical harmonic coefficients well determined through 
        degree and order 10, providing the first detailed view of a planetary dynamo beyond Earth.</Description>
