Ceilometer cloud base height measurements taken at Summit Station, Greenland - Arctic Observing Network program

This data set contains measurements from a Vaisala ceilometer 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 ceilometer points near-vertically and provides estimates of cloud base height (for up to three layers) and the total visibility, based on Vaisala's proprietary algorithm. Detailed information on these parameters and other aspects of the dataset are included in the netCDF header information for each file. The ceilometer is owned by the Department of Energy Atmospheric Radiation Measurement Program. Field operations support is provided 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）的维萨拉（Vaisala）云高仪（ceilometer）的观测数据，该设备是格陵兰顶站能量、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。该云高仪采用近乎垂直的指向模式，基于维萨拉的专有算法，可估算云底高度（最多可识别三层云系）以及总能见度。上述参数及数据集其他相关细节均收录于各文件的netCDF文件头信息中。该云高仪归属于美国能源部大气辐射测量项目（Department of Energy Atmospheric Radiation Measurement Program），野外作业支持由美国国家科学基金会北极观测网络（Arctic Observing Network, AON）项目提供。
