Hydroxyl (OH) airglow image data, Alaska, April 21, 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.

各类气辉辐射的图像数据以.png格式存储。文件名包含观测站点（PFRR，即Poker Flat Research Range，扑克弗拉特研究靶场）、图像采集启动时的观测时间（年、月、日、时、分、秒），末尾为辐射标识（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，其中包含高质量、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成果时无需将我们列为共同作者，但我们仍建议用户联系项目首席研究员（PI, Principal Investigator）以确保对数据的解读准确无误，否则请遵循标准科研伦理规范。
