北京延庆站激光雷达反演大气密度数据（2010年）

本数据来源于子午工程北京延庆站，是利用激光雷达的瑞利散射的光子计数数据，反演得到了30~60km高度的大气密度数据，主要包括高度和大气密度数据，文件以文本格式存储，数据文件数目取决于实际观测数。该数据对中高层大气光化学、动力学过程以及日地系统耦合机制过程探究有重要作用。观测站位于北京科技职业学院院内，由中国科学院国家空间科学中心与北京科技职业学院合作建设。台站地理纬度为40.47°N，经度为115.97°E ，海拔高度460m。

This dataset is sourced from the Beijing Yanqing Station of the Meridian Space Weather Monitoring Project. It is derived from photon counting data collected via Rayleigh scattering by a lidar, yielding atmospheric density measurements at altitudes between 30 km and 60 km. The dataset mainly includes altitude and atmospheric density data, stored in plain text format, with the number of data files varying according to actual observation campaigns. This dataset holds significant value for investigations into middle and upper atmospheric photochemistry, dynamic processes, and solar-terrestrial system coupling mechanisms. The station is located on the campus of Beijing College of Science and Technology, and was jointly built by the National Space Science Center of the Chinese Academy of Sciences and Beijing College of Science and Technology. Its geographic coordinates are 40.47°N latitude, 115.97°E longitude, with an elevation of 460 meters.
