We develop two related models of magnetosphere-ionosphere\udcoupling in the jovian system by combining previous models defined at\udionospheric heights with magnetospheric magnetic models that allow system\udparameters to be extended appropriately into the magnetosphere. The key\udfeature of the combined models is thus that they allow direct connection to\udbe made between observations in the magnetosphere, particularly of the\udazimuthal field produced by the magnetosphere-ionosphere coupling currents\udand the plasma angular velocity, and the auroral response in the ionosphere.\udThe two models are intended to reflect typical steady-state sub-corotation\udconditions in the jovian magnetosphere, and transient super-corotation\udproduced by sudden major solar wind-induced compressions, respectively. The\udkey simplification of the models is that of axi-symmetry of the field, flow,\udand currents about the magnetic axis, limiting their validity to radial\uddistances within ~30 <I>R<sub>J</sub></I> of the planet, though the magnetic axis\udis appropriately tilted relative to the planetary spin axis and rotates with\udthe planet. The first exploration of the jovian polar magnetosphere is\udplanned to be undertaken in 2016–2017 during the NASA New Frontiers Juno\udmission, with observations of the polar field, plasma, and UV emissions as a\udmajor goal. Evaluation of the models along Juno planning orbits thus\udproduces predictive results that may aid in science mission planning. It is\udshown in particular that the low-altitude near-periapsis polar passes will\udgenerally occur underneath the corresponding auroral acceleration regions,\udthus allowing brief examination of the auroral primaries over intervals of\ud~1–3 min for the main oval and ~10 s for narrower polar\udarc structures, while the "lagging" field deflections produced by the\udauroral current systems on these passes will be ~0.1°, associated\udwith azimuthal fields above the ionosphere of a few hundred nT
