珠峰站激光雷达反演气溶胶消光系数廓线数据（2018-2019）

本数据集是珠峰站激光雷达观测的大气气溶胶消光系数廓线。对激光雷达探测到的原始数据利用Fernald方法进行反演。反演过程中雷达比固定为30 Sr，假定与距离无关的雷达比可能引起的反演误差约在5-12%。激光雷达盲区和过渡区分别在0.1 km和0.3 km。时间分辨率5-20分钟，垂直分辨率7.5m，最大高度约2km。观测数据包括2018年3月、7月、11月以及2019年的1月。这些数据可用于评估高原上气溶胶垂直特征，进一步可用于量化高原气溶胶输送特征。

This dataset contains atmospheric aerosol extinction coefficient profiles observed by the lidar at the Mount Qomolangma Station. The raw data collected by the lidar were retrieved via the Fernald inversion method. The lidar ratio was set to a constant value of 30 Sr throughout the retrieval process, and the retrieval error induced by the assumption of range-independent lidar ratio is estimated to be approximately 5–12%. The blind zone and transition zone of the lidar are 0.1 km and 0.3 km, respectively. The temporal resolution ranges from 5 to 20 minutes, the vertical resolution is 7.5 m, and the maximum observable height is approximately 2 km. The observational data cover March, July, and November 2018, as well as January 2019. This dataset can be used to evaluate the vertical characteristics of aerosols over the Qinghai-Tibet Plateau, and further quantify the transport characteristics of plateau aerosols.
