Hydroxyl (OH) airglow image data, Alaska, February 9, 2011

Airglow image data of various emissions are stored in .png image format. The filename indicates the observation site (PFRR = Poker Flat Research Range), the observation time (year, month, day, hour, min, and sec) of image acquisition start, and finally the emission identifier follows (for example OH or Na). Please note that this data set is the RAW data and contain the entire set of images obtained during the project period. This include high, medium, and low quality image data. While we do not require co-authorship in publications using the data set, we encourage users to contact the PI to make sure the data has been interpreted correctly. Otherwise, standard scientific ethic is expected.各类气辉辐射的图像数据以.png格式存储。文件名包含观测站点信息（PFRR = Poker Flat Research Range，波克弗拉特研究靶场）、图像采集起始时刻的观测时间（年、月、日、时、分、秒），末尾标注辐射种类标识（例如OH或Na）。请注意，本数据集为原始RAW数据，涵盖项目周期内获取的全部图像文件，包含高质量、中等质量与低质量的各类图像数据。尽管使用本数据集发表学术成果无需将数据集提供方列为共同作者，但我们鼓励使用者联系项目首席研究员（Principal Investigator，PI）以确保数据解读的准确性。若未遵循此指引，请遵守标准科研伦理规范。
