神舟三号大气成分数据

本数据集为载人航天工程中神舟三号飞船（SZ-3）搭载的大气成分探测器（Atmospheric Ingredient Detector）观测到飞船轨道高度（320~400km）的氮原子，氮分子和氧原子数密度数据。数据覆盖的时间范围为2002年4月25至2002年6月14日，时间精度为20s。数据用文本格式存储，包含两个部分：文件头和数据区。本数据集可用于科学研究和工程应用，是低轨道卫星轨道设计、姿态控制等研究的重要数据，也常用于研究太阳活动、地磁活动对热层大气密度的影响。

This dataset contains number density data of nitrogen atoms, nitrogen molecules and oxygen atoms, measured by the Atmospheric Ingredient Detector carried on the Shenzhou-3 (SZ-3) spacecraft as part of the Chinese Manned Space Engineering program. The spacecraft operates at an orbital altitude between 320 km and 400 km. The data covers the period from April 25, 2002 to June 14, 2002, with a time resolution of 20 seconds. Stored in a text format, the dataset consists of two components: a file header and a data section. This dataset can be utilized for both scientific research and engineering applications, and acts as critical data for studies such as low Earth orbit (LEO) satellite orbital design and attitude control. It is also commonly employed to investigate the impacts of solar activity and geomagnetic activity on thermospheric atmospheric density.
