Hydroxyl (OH) airglow image data, Alaska, March 7, 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图像格式存储。文件名可体现图像采集起始时刻的观测站点（PFRR = Poker Flat Research Range）、观测时间（年、月、日、时、分、秒），最终字段为辐射标识（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，包含高质量、中等质量及低质量的所有图像数据。尽管使用本数据集发表学术成果时，我们不要求使用者将我方列为共同作者，但我们鼓励使用者联系项目首席研究员（PI，Principal Investigator）以确认数据解读无误。若未遵循此建议，请务必恪守标准科学伦理规范。
