Ceilometer Cloud Base Height Measurements at Summit Station, Greenland, 2012

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岛萨米特站（Summit Station）的维萨拉（Vaisala）云高仪的观测数据，该设备隶属于“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，缩写ICECAPS）项目。该云高仪以近乎垂直的角度指向天空，基于维萨拉专有算法，可估算最多三层云的云底高度与总能见度。本数据集的各项参数及其他相关细节，均收录于每个文件的netCDF（网络通用数据格式）头文件信息中。该云高仪归美国能源部大气辐射测量计划（Department of Energy Atmospheric Radiation Measurement Program）所有，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，缩写AON）计划提供。
