Data for "An inversion of magnetic field measurements to constrain the depth, thickness, and conductivity of Europa's ocean" by Winkenstern et al. (2025)

This dataset contains the simulation output used in our inversion of Galileo magnetic field measurements to quantitatively characterize and constrain the depth, thickness, and electrical conductivity of Europa's subsurface ocean. The method developed in this study was applied to the E04 and E14 flyby, assuming a radially symmetric O2 atmosphere. Simulations with column densities ranging from 1e14 to 4e14 cm^-2 are provided in this dataset for both flybys. For the E14 flyby, additional simulations were performed under consideration of an asymmetric atmosphere, motivated by variabilities in column density due to upstream-downstream-asymmetries, as well as day-night-asymmetries.本数据集包含用于反演伽利略（Galileo）磁场测量数据的模拟结果，以定量表征并约束木卫二（Europa）次表层海洋的深度、厚度与电导率。本研究开发的方法被应用于E04与E14飞掠任务场景，假设存在径向对称的氧气（O₂）大气。本数据集为两次飞掠任务均提供了柱密度介于1×10¹⁴ 至 4×10¹⁴ cm⁻²之间的模拟结果。针对E14飞掠任务，本数据集额外纳入了考虑非对称大气的模拟结果，该设置旨在匹配由上下游不对称性与昼夜不对称性引发的柱密度变化。
