Radiosonde temperature and humidity profiles taken at Summit Station, Greenland, 2024

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 and its follow-on projects ICECAPS-ACE and ICECAPS-MELT. 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. Starting around 2020 the radiosonde program has periodically dropped to one sounding per day, with some periods of no soundings per day, based on funding limitations. 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.

本数据集收录了由维萨拉无线电探空仪（Vaisala radiosondes）获取的温湿度廓线数据。作为格陵兰萨米特站能量、云、大气状态与降水综合表征（ICECAPS）项目及其后续项目ICECAPS-ACE、ICECAPS-MELT的组成部分，该探空仪系统通常每日发射两次探空仪。早期的无线电探空观测数据初始未包含风场追踪信息，2011年7月起逐步过渡为每份数据中纳入1台探空仪的风场追踪数据，随后于2014年6月实现每日两次的风场追踪探空观测。2020年前后，受经费限制，该探空项目一度缩减为每日1次探空，部分时段甚至出现每日无探空作业的情况。本数据集采用维萨拉标准处理软件完成数据预处理与整编。各文件的netCDF头文件中，详细记载了本数据集涉及的各类参数及其他相关细节信息。
