There is ample evidence for magnetic reconnection in the solar system, but it is a nontrivial task to visualize, to determine the proper approaches and frames to study, and in turn to elucidate the physical processes at work in reconnection regions from in-situ measurements of plasma particles and electromagnetic fields. Here an overview is given of a variety of single- and multi-spacecraft data analysis techniques that are key to revealing the context of in-situ observations of magnetic reconnection in space and for detecting and analyzing the diffusion regions where ions and/or electrons are demagnetized. We focus on recent advances in the era of the Magnetospheric Multiscale mission, which has made electron-scale, multi-point measurements of magnetic reconnection in and around Earth's magnetosphere.
太阳系中存在磁重联的充分证据,但要实现可视化、确定合适的研究方法和框架,进而从等离子体粒子和电磁场的原位测量中阐明重联区域中起作用的物理过程,并非易事。本文概述了各种单航天器和多航天器数据分析技术,这些技术对于揭示太空中磁重联原位观测的背景以及检测和分析离子和/或电子去磁的扩散区域至关重要。我们重点关注磁层多尺度任务时代的最新进展,该任务对地球磁层及其周围的磁重联进行了电子尺度的多点测量。
