中国第35次南极科学考察（2018-2019年）中山站极光CCD成像系统数据

我国南极中山站（地理坐标：69.4˚ S，76.4˚ E，修正地磁纬度为-74.5˚ MLAT）白天经过磁层极隙区，晚上处在极盖区，可以观测到丰富的日地能量传输过程的电离层征兆和极光现象，是开展空间资源业务化监测和极区高空大气物理现象观测研究的理想场所。
本数据为第35次南极考察（2019年）中山站极光CCD成像系统采集的全天空极光监测数据，对中山站及周边方圆500km区域的极光强度分布和形态进行监测。对研究日地能量注入过程以及空间环境监测有重要意义。

南极中山站及周边500km全天空区域

China's Antarctic Zhongshan Station (geographic coordinates: 69.4° S, 76.4° E, corrected geomagnetic latitude: -74.5° MLAT) passes through the magnetospheric cusp region during the daytime and lies within the polar cap region at night, where abundant ionospheric signatures and auroral phenomena related to solar-terrestrial energy transfer processes can be observed. It is an ideal site for operational monitoring of space resources and observational research on polar upper atmospheric physical phenomena.

This dataset comprises all-sky auroral monitoring data collected by the Zhongshan Station auroral CCD imaging system during the 35th Chinese National Antarctic Research Expedition (2019), which monitors the auroral intensity distribution and morphology over a 500-kilometer radius around Zhongshan Station. This dataset is of great significance for studies of solar-terrestrial energy injection processes and space environment monitoring.
