Initial Results From a Non-Hydrostatic Jupiter Ionosphere-Thermosphere Global Model

We present the first results from a newly developed 3-D global model for the Jovian Ionosphere-thermosphere system, which is called the Jupiter Global Ionosphere-Thermosphere Model (J-GITM). We compare simulated fields with the results from previous 3-D Jupiter upper atmospheric modeling. We also explore the adaptation of this model to Saturn, emphasizing the global thermal structure calculations. In particular, we examine the role of high-latitude magnetospheric inputs (e.g., joule heating and energetic particle precipitation) on the global energy budget of the giant planets.
