SOnic Detection And Ranging (SODAR) measurements taken at Summit Station, Greenland, 2020

This data set contains measurements from a sodar 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 sodar operates at 2100 Hz and points vertically. Reflectivity measurements from the system are used to characterize gradients in the lower atmosphere that provide information on the boundary layer depth. Data files including the relative backscatter. Detailed information on file parameters and other aspects of the dataset are included in the netCDF header information for each file. The sodar is owned by the National Oceanic and Atmospheric Administrations's Earth System Research Laboratory. Field operations are supported by the National Science Foundation's Arctic Observing Network (AON) Program.本数据集包含部署于格陵兰顶站（Summit Station）的声雷达（sodar）采集的测量数据，该设备是「格陵兰顶能量、云、大气状态与降水综合表征」（Integrated Characterization of Energy, Clouds, Atmospheric State, and Precipitation at Summit，简称ICECAPS）项目的组成部分。该声雷达工作频率为2100赫兹，采用垂直指向模式。系统采集的反射率测量数据可用于表征低层大气的梯度特征，进而提供边界层高度相关信息。数据文件包含相对后向散射相关内容，各文件的参数细节与数据集其他相关信息，均存储于每个文件的netCDF文件头信息中。该声雷达由美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）地球系统研究实验室所有并维护。野外作业由美国国家科学基金会（National Science Foundation）北极观测网络（Arctic Observing Network, AON）项目提供支持。
