神舟二号大气密度数据

本数据集为载人航天工程中神舟二号飞船（SZ-2）搭载的大气密度探测器（Atmospheric Density Detector）观测到飞船轨道高度（370~400km）的中性大气数密度和质量密度数据。数据覆盖的时间范围为2001年1月16日至2001年4月10日，时间精度为8s。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 neutral atmospheric number density and mass density data measured by the Atmospheric Density Detector onboard the Shenzhou-2 (SZ-2) spacecraft, which participated in the China Manned Space Program, at an orbital altitude of 370–400 km. The data covers the time period from January 16, 2001 to April 10, 2001, with a temporal resolution of 8 seconds. Stored in plain text format, the dataset consists of two parts: the file header and the data section. This dataset can be utilized for both scientific research and engineering applications, serving as critical data for studies including low-Earth orbit satellite orbital design and attitude control. It is also frequently used to explore the impacts of solar and geomagnetic activities on thermospheric atmospheric density.
