Ceilometer measurements

This data set contains measurements from a Vaisala ceilometer that is deployed at Summit Station, Greenland. 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.

本数据集收录了部署于格陵兰顶峰站（Summit Station）的维萨拉（Vaisala）云高仪的观测数据。该云高仪以近垂直姿态指向天空，依托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。各文件的netCDF（Network Common Data Form）头文件中收录了本数据集相关参数及其他细节信息。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（AON）计划提供。
