All the lightning data of the manuscript "High‐speed video observations of needles evolving and not evolving into negative leaders in a positive cloud-to-ground lightning flash" submitted to Geophysical Research Letters

The data supports the manuscript entitled “High‐speed video observations of needles evolving and not evolving into negative leaders in a positive cloud-to-ground lightning flash”. The high-speed video data files of the positive cloud-to-ground lightning (20200603_082539, denoted F20065) of *.cih and *.avi can be opened by Photron Camera Control software (Photron Fastcam Viewer) that can be download from this link: https://photron.com/photron-support/ In addition, MATLAB can open the *.mat file (electric field change data), and Excel can open the *.xlsx file (Guangdong-Hong Kong-Macao Lightning Location data (20200603082523-20200603082556). The data can be used freely for scientific purposes with the appropriate citation.

本数据集支撑题为《正地闪中针状结构演化与不演变为负先导的高速视频观测》的学术论文。该正云地闪（positive cloud-to-ground lightning）的高速视频数据文件（编号20200603_082539，记为F20065）涵盖*.cih与*.avi两种格式，可通过Photron相机控制软件（Photron Fastcam Viewer）读取，该软件可从以下链接下载：https://photron.com/photron-support/。此外，*.mat格式文件（电场变化数据）可通过MATLAB读取，*.xlsx格式文件（粤港澳闪电定位数据，时间跨度为2020年6月3日08时25分23秒至2020年6月3日08时25分56秒）可通过Excel读取。本数据集可免费用于科学研究，但需恰当引用相关文献。
