Simultaneous measurements of solar wind from L1, shocked solar wind from Magnetosheath, and measures of geomagnetic response from ground-based indices

These data are compiled from other sources and are used in the calculations and simulations for the paper "Regression to the Mean of Extreme Geomagnetic Storms". Data.zip contains the curated data set of simultaneous measurements from L1 satellites and ground-based measurements. It also contains Simultaneous measurements made in the Magnetosheath, and upstream of the bow-shock, with time stamp, satellite ID, and Kan-Lee electric field values. The methodology used to create these magnetosheath measurements is described by Michotte de Welle et al. (2024). We have presented the minimal necessary data to reproduce the results. Here are the acknowledgements of the primary data sources: All data we have used is publicly available. We thank GSFC/SPDF OMNIWeb service for the WIND spacecraft measurements. The WIND spacecraft measurements of the solar wind propagated to the bow shock can be accessed from https://spdf.gsfc.nasa.gov/pub/data/omni/high_res_omni/sc_specific/. The MMS, Cluster, DoubleStar, and THEMIS data can be accessed from the GSFC/SPDF web service https://spdf.gsfc.nasa.gov/. The polar cap index values PCN and PCS were downloaded from https://pcindex.org/archive. We thank Dr. Oleg Troshichev of the Arctic and Antarctic Research Institute for this data (https://pcindex.org/contacts). The auroral electrojet indices were downloaded from the SuperMAG database https://supermag.jhuapl.edu/indices/. For SuperMAG indices, we gratefully acknowledge the SuperMAG collaborators (https://supermag.jhuapl.edu/info/?page=acknowledgement).本数据集编译自其他公开来源，用于论文《极端地磁暴向均值回归》（Regression to the Mean of Extreme Geomagnetic Storms）的计算与仿真工作。 Data.zip 中包含经整理的L1卫星同步观测数据与地面台站观测数据集，同时收录了磁鞘区与弓激波上游的同步观测数据，包含时间戳、卫星标识符及Kan-Lee电场 (Kan-Lee electric field) 值。用于生成上述磁鞘区观测数据的方法由Michotte de Welle等人（2024）进行了详细阐述。本数据集提供了复现该论文结果所需的最小必要数据。 以下为原始数据来源的致谢说明： 本研究使用的全部数据均为公开可得数据。我们感谢GSFC/SPDF OMNIWeb服务提供的WIND航天器观测数据。经传播至弓激波位置的太阳风WIND航天器观测数据可从https://spdf.gsfc.nasa.gov/pub/data/omni/high_res_omni/sc_specific/ 获取。MMS、Cluster、DoubleStar及THEMIS数据可通过GSFC/SPDF官方服务平台https://spdf.gsfc.nasa.gov/ 获取。极盖指数PCN与PCS值从https://pcindex.org/archive 下载获取。我们感谢北极与南极研究所的Oleg Troshichev博士提供该数据集（https://pcindex.org/contacts）。极光电射流指数从SuperMAG数据库https://supermag.jhuapl.edu/indices/ 下载获取。对于SuperMAG指数，我们衷心感谢SuperMAG协作团队（https://supermag.jhuapl.edu/info/?page=acknowledgement）。
