Substorm Onsets and Phases (SOPHIE), 1990-2022, EPT 80

Outputs from the SOPHIE (Forsyth et al., 2015, 10.1002/2015JA021343) substorm onset and phase detection technique for SuperMAG data between 1990 and 2022 (inclusive).This version has been updated in to include the MLT and MLAT of the SuperMAG station providing the SML data and as well as the change of SML during the phase (SML_change) value of SML at the end of each phase (SML_min)This file provides the start times of growth/energy input, expansion and recovery phases determined by SOPHIE for an EPT of 80.Data generated for "A Statistical Study of the Properties of and Geomagnetic Responses to Large, Rapid Southward Turnings of the Interplanetary Magnetic Field" by Lazzeri et al., submitted to J. Geophys. Res.The data is presented in 7 columns: -The date and time of the first data point in the given phase (YYYY/MM/DD-HH:MM:SS)The phase number (1 for growth/energy input, 2 for expansion, 3 for recovery)A flag indicating that the rate of change of SMU is similar to that of SML in the expansion phase (0 for no flag, 1 for flag)MLT of the active SML station at the shown timeMLAT of the active SML station at the shown timeThe change in SML from the start of the phase to the end of the phase (i.e. from the time given on that line to the time given on the following line)The value of SML at the end of the phase.The original SuperMAG indices can be downloaded from https://supermag.jhuapl.edu/

本数据集为基于SOPHIE（Forsyth等，2015，DOI: 10.1002/2015JA021343）亚暴起始与相位识别算法，针对1990年至2022年（含首尾年份）的SuperMAG数据生成的处理结果。本次更新版本新增了提供SML指数的SuperMAG台站的磁地方时（MLT）与磁纬度（MLAT）参数，同时补充了各相位期间的SML变化量（SML_change）以及各相位结束时刻的SML极小值（SML_min）。本文件给出了当阈值为80的EPT事件发生时，由SOPHIE算法识别得到的增长/能量输入相、扩张相与恢复相的起始时刻。本数据集为Lazzeri等提交至J. Geophys. Res.的论文"A Statistical Study of the Properties of and Geomagnetic Responses to Large, Rapid Southward Turnings of the Interplanetary Magnetic Field"所生成的科研数据。数据集共包含7列信息，具体如下：1. 对应相位内首个数据点的日期与时间（格式为YYYY/MM/DD-HH:MM:SS）；2. 相位编号（1代表增长/能量输入相，2代表扩张相，3代表恢复相）；3. 标识位：用于标记扩张相中SMU变化率与SML变化率相近的情况（0表示无标记，1表示存在标记）；4. 对应时刻活跃SML台站的磁地方时（MLT）；5. 对应时刻活跃SML台站的磁纬度（MLAT）；6. 该相位自起始至结束期间的SML变化量（即本行记录时刻至下一行记录时刻的SML差值）；7. 该相位结束时刻的SML数值。原始SuperMAG指数可从https://supermag.jhuapl.edu/ 下载获取。
