Radiosonde temperature and humidity profiles taken at Summit Station, Greenland, 2021

This data set contains profiles of temperature and humidity observed by Vaisala radiosondes that are launched nominally twice daily at Summit Station, Greenland as part of the Integrated Characterization of Energy, Clouds, Atmospheric state, and Precipitation at Summit (ICECAPS) Project. These radiosonde measurements did not initially contain wind tracking information, but transitioned towards including wind tracking in one sonde per data starting in 7/2011, then moving to twice-daily wind sondes in 6/2014. The data are processed using the standard Vaisala processing software. Detailed information on these parameters and other aspects of the dataset are included in the netCDF header information for each file.

本数据集收录了维萨拉（Vaisala）无线电探空仪（radiosonde）获取的温湿度廓线数据。作为“格陵兰能源、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）”项目的组成部分，这些探空仪在格陵兰萨米特站（Summit Station）常规每日发射两次。早期的探空观测数据未包含风场追踪信息；2011年7月起，每份观测数据对应的探空仪中开始纳入风场追踪功能，至2014年6月，改为每日两次发射的探空仪均具备风场追踪能力。本数据集采用维萨拉标准处理软件完成数据处理。各文件的netCDF（网络通用数据格式）头文件中，包含了本数据集各参数及其他相关细节信息。
