Hydroxyl (OH) airglow image data, Alaska, April 20, 2012

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（Airglow）辐射图像数据以.png格式存储。文件名依次标注了观测站点（PFRR，即扑克弗拉特研究靶场（Poker Flat Research Range））、图像采集起始时刻的观测时间（年、月、日、时、分、秒），最后为辐射标识（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，包含高、中、低质量的各类图像文件。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，但我们建议使用者联系项目首席研究员（Principal Investigator，简称PI）以确保数据解读的准确性，除此以外需遵循标准科学伦理准则。
