Cloud and Aerosol Polarization and Backscatter LiDAR measurements taken at Summit Station, Greenland, 2020

This data set contains measurements from a Cloud and Aerosol Polarization and Backscatter LiDAR (CAPABL) that is deployed at Summit Station, Greenland as part of the Integrated Characterization of Energy, Clouds, Atmospheric state, and Precipitation at Summit (ICECAPS) Project. This LiDAR points near-vertically and measures backscatter in three polarization states. Parameters include: backscatter in the parallel channel, the depolarization ratio, and the diattenuation. Detailed information on these parameters and other aspects of the dataset are included in the netCDF header information for each file. The LiDAR is owned by the National Oceanic and Atmospheric Administration's Earth System Research Laboratory. Field operations support is provided by the National Science Foundation's Arctic Observing Network (AON) Program.

本数据集包含搭载于格陵兰萨米特站（Summit Station）的云与气溶胶偏振后向散射激光雷达（Cloud and Aerosol Polarization and Backscatter LiDAR, CAPABL）的观测数据，该设备作为格陵兰萨米特站能量、云、大气状态与降水综合表征（Integrated Characterization of Energy, Clouds, Atmospheric State, and Precipitation at Summit, ICECAPS）项目的组成部分部署于此。该激光雷达采用近垂直指向方式，可测量三种偏振态下的后向散射信号。观测参数包括平行通道后向散射、退偏振比以及二向衰减量。本数据集各文件的netCDF文件头信息中，收录了上述参数及数据集其他相关细节的完整说明。该激光雷达归美国国家海洋和大气管理局地球系统研究实验室所有。美国国家科学基金会北极观测网（Arctic Observing Network, AON）项目为本次野外作业提供支持。
