Dataset supporting the University of Southampton doctoral Thesis "Observational and simulation studies of the structure of Earth's magnetotail during periods of northward IMF" by Laura Fryer. This dataset contains a movie created to support the description of the analysis in Chapter 4. The movie contains the entire simulation run at a 5-minute resolution, where each time shows a 3D plot of solar wind and magnetospheric field lines from the simulation run in GUMICS. The Figures are referenced from the time since the IMF By sign change passed the nose of the magnetopause. The background colour indicates the log of the magnitude of the magnetic field strength in the X-Y and X-Z planes. The field line traces are shown in orange. The field lines have each been traced using the same starting points, at 10 RE intervals down the X axis, and additionally in a spherical shell above 60 latitude (in 10 increments) and in 45 longitude increments around the ionospheric boundary (at a radius of 3.7 RE). Note that as a consequence, we choose to observe the change in topology at set locations within the modelled magnetosphere, rather than the propagation of the same magnetic field lines throughout the run.

本数据集用于支撑南安普顿大学Laura Fryer的博士论文《北向行星际磁场（Interplanetary Magnetic Field, IMF）期间地球磁尾结构的观测与模拟研究》。本数据集包含一段用于辅助说明第4章分析内容的可视化影片。该影片以5分钟为时间分辨率完整呈现了整个GUMICS模拟过程，每一帧均为基于该模拟得到的太阳风与磁层磁场线的三维绘图。所有绘图均以IMF By分量符号反转经过磁层顶（magnetopause）鼻部的时刻作为时间基准进行标注。背景色用于表征X-Y平面与X-Z平面内磁场强度幅值的对数值，磁场线轨迹以橙色绘制。所有磁场线均采用统一起始点进行追踪：沿X轴以10个地球半径（Earth Radii, RE）为间隔采样，同时在纬度60°以上的球壳区域（以10°为增量）以及半径3.7 RE的电离层边界周围，以45°为经度增量进行采样。请注意，本研究因此选择在模拟磁层内的固定位置观测拓扑结构变化，而非追踪同一条磁场线在整个模拟过程中的传播过程。Laura Fryer（缩写LJF）的研究得到英国科学与技术设施理事会（Science and Technology Facilities Council, STFC）的学生资助项目ST/T506424/1（编号2279917）支持。授权协议：知识共享署名（CC-BY）
