Pulsating Aurora Database and Automated Algorithm for Detecting them from Ground-Based Optical Imaging

This contains the original pulsating auroral data used by the paper 'Pulsating Aurora Database and Automated Algorithm for Detecting them from Ground-Based Optical Imaging', which will appear in Frontiers in Astronomy and space sciences. This dataset contains a master catalog of auroral pulsation detections derived from ground-based all-sky imager observations, along with representative video and image files illustrating the underlying data products. The primary file, Pulsating_Aurora_event_list.txt, is a plain-text table summarizing automatically detected auroral pulsation events. For each event, the report lists the start and end times, corresponding image frame numbers, peak frame number, integrated intensity metrics (both median absolute deviation–normalized and raw), spatial region identifier, full width at half maximum (FWHM) duration in seconds, FWHM start and end frames, and the source TIFF file from which the event was extracted. The report was generated on 2026-01-07 using auroral image data from the groudn based auroral imager in Foker Flat, Alaska station. In addition to the report, the dataset includes: Three auroral video files (V_120813_03_39_53_13_9_1x.mp4, V_010714_16_02_23_19_8_1x.mp4, and V_010714_16_15_53_33_15_1x.mp4) that provide visual examples of auroral activity and pulsation behavior observed during selected intervals shown in Figure-1(a-b and e-f). One example TIFF image file (THA140107_15595711_16bit.tif) containing raw auroral image data representative of the inputs used in the pulsation detection analysis shown in Figure-1(a-b and e-f). The dataset is intended for use in space physics and auroral research, particularly studies of pulsating aurora and related magnetospheric processes.本数据集包含即将发表于《天文学与空间科学前沿（Frontiers in Astronomy and Space Sciences）》的论文《脉动极光数据库与地基光学成像自动检测算法（Pulsating Aurora Database and Automated Algorithm for Detecting them from Ground-Based Optical Imaging）》所使用的原始脉动极光数据。 本数据集包含基于地基全天空成像仪观测得到的极光脉动检测主目录，以及用于展示核心数据产物的代表性视频与图像文件。 核心文件为Pulsating_Aurora_event_list.txt，该纯文本表格汇总了自动检测得到的极光脉动事件。针对每一次事件，该列表记录了事件的起始与结束时间、对应图像帧编号、峰值帧编号、积分强度指标（经中位绝对偏差归一化处理与原始值）、空间区域标识符、半高全宽（Full Width at Half Maximum, FWHM）持续时长（单位：秒）、半高全宽起止帧，以及提取该事件的源TIFF文件。本列表于2026年1月7日生成，所用极光图像数据来自阿拉斯加州福克斯弗拉特（Foker Flat）地基极光成像站获取的数据。 除上述列表文件外，本数据集还包含： 1. 三段极光视频文件（V_120813_03_39_53_13_9_1x.mp4、V_010714_16_02_23_19_8_1x.mp4、V_010714_16_15_53_33_15_1x.mp4），用于直观展示图1(a-b、e-f)中选定时段内观测到的极光活动与脉动特征； 2. 一张示例TIFF图像文件（THA140107_15595711_16bit.tif），包含用于脉动检测分析的原始极光图像数据，对应图1(a-b、e-f)中的输入数据示例。 本数据集适用于空间物理与极光研究领域，尤其是针对脉动极光及相关磁层过程的相关研究。
