中国第37次南极科学考察（2020-2021年）中山站极光全天空成像观测数据

本数据集包括极光全天空成像630.0nm和557.7nm原始图像数据，由中国第37次南极科学考察中山站科考队员在南极现场观测获取。根据太阳高度角和现场天气情况确定开机观测时段，通常在太阳高度角低于-8度时的晴朗夜间进行观测，采样曝光时间4s，转存时间1-2s，数据时间间隔12s。

This dataset contains raw all-sky auroral imaging data at wavelengths of 630.0 nm and 557.7 nm, which was collected by the scientific expedition team from the 37th Chinese Antarctic Scientific Expedition during in-situ observations at Zhongshan Station in Antarctica. The observation periods are determined based on solar elevation angle and on-site weather conditions, typically conducted on clear nights when the solar elevation angle is lower than -8 degrees. The sampling exposure time is 4 seconds, the data transfer and storage time ranges from 1 to 2 seconds, and the temporal interval between consecutive data records is 12 seconds.
