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SOPHIE亚暴起始与相位识别技术（Forsyth等，2015，DOI:10.1002/2015JA021343）针对1990年至2022年（含首尾年份）SuperMAG数据生成的处理结果。本版本已完成更新，新增了提供SML指数的SuperMAG台站的磁地方时（Magnetic Local Time, MLT）与磁纬（Magnetic Latitude, MLAT）信息，同时包含各相位的SML变化量（SML_change）与相位末期的SML极小值（SML_min）。本文件包含了SOPHIE针对EPT为80的情况识别得到的增长/能量输入相、扩张相与恢复相的起始时刻。本数据集为Lazzeri等人提交给《Journal of Geophysical Research》的论文《大尺度快速南向行星际磁场转向的特性及其地磁响应统计研究》所生成。数据以7列形式呈现：1. 给定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：用于指示扩张相内SMU的变化率与SML变化率相近（0代表无标识，1代表存在标识）；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（MLAT）；6. 相位起始至相位结束（即当前行对应时刻至下一行对应时刻）期间的SML变化量；7. 相位末期的SML数值。原始SuperMAG指数可从https://supermag.jhuapl.edu/ 下载。
