摘要
在2016年7月抵达木星后,朱诺号对木星极轨道高度偏心的磁层(特别是赤道等离子盘区域)进行了全球调查。从那时起,JADE仪器积累了大量的等离子体测量。利用开发的正演建模方法和CU Boulder的Alpine超级计算机集群,我们拟合了PJ5到PJ56之间10到50 R J ${\mathrm{R}}_{\mathrm{J}}$的所有离子测量值,得到了一个具有70,487个良好拟合的数据集,该数据集由以下等离子体参数组成:不同重离子的丰度、密度、温度和重离子的三维体流速度。通过对数据集的概述和在磁通管交换上的应用实例来说明其有效性和实用性。在发生在~ ${\sim} $ 14 R J ${\mathrm{R}}_{\mathrm{J}}$的交换事件中,等离子体盘是可变的和加热的,有较热的流入和较冷的流出交替发生,伴随着磁场的小扰动。该数据集具有许多应用的潜力。
Ion Parameters Dataset From Juno/JADE Observations in Jupiter's Magnetosphere Between 10 and 50 RJ
After its arrival at Jupiter in July 2016, Juno conducted a global survey of Jupiter's magnetosphere (especially the equatorial plasma disk region) with its highly eccentric polar orbit. Since then, the JADE instrument has accumulated a large amount of plasma measurements. Using a developed forward modeling method and the Alpine supercomputer cluster at CU Boulder, we fit all ion measurements between 10 and 50 from PJ5 to PJ56, obtaining a dataset with 70,487 good fits that consists of the following set of plasma parameters: abundances of different heavy ions, density, temperature, and 3-D bulk flow velocity of heavy ions. An overview of the dataset and an example use on flux tube interchange are presented to illustrate its effectiveness and usefulness. In the investigated interchange event that occurred at 14 , the plasma disk is variable and heated, with alternating hotter inflows and colder outflows, accompanied by small perturbations in the magnetic fields. This dataset has the potential for many applications.
