中国第31次南极科学考察(2014-2015年)中山站极光光谱仪观测数据

本数据集为极光光谱仪原始观测数据，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15s，转存时间5s，数据时间间隔20s。本数据集由中国第31次南极科学考察中山站科考队员在南极现场观测获取。

This dataset contains raw observational data acquired by an auroral spectrograph. The observation periods are determined based on the 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 15 seconds, and the data transfer duration is 5 seconds, resulting in a temporal interval of 20 seconds between consecutive data samples. This dataset was collected by the scientific expedition members from China's 31st Antarctic Scientific Expedition during in-situ observations at the Zhongshan Station in Antarctica.
