High resolution radiosonde measurements from station Ny-Ålesund (2025-02)@en

At AWIPEV research base in Ny-Ålesund, Svalbard, regular radiosonde launches are operated once per day. The launch frequency may increase to 6-hourly soundings during specific campaign periods. The Vaisala RS41-SGP radiosondes provide data of pressure, temperature, relative humidity, wind speed and wind direction from ground to about 30 km height. The given data set contains vertical profiles with 1-second time resolution data as obtained by the manufacturer's data processing, quality controlled for appropriate physical ranges.在斯瓦尔巴群岛新奥尔松的AWIPEV研究基地，常规无线电探空仪（radiosonde）施放作业每日开展一次。在专项科考时段，探空施放频率可提升至每6小时一次。维萨拉（Vaisala）RS41-SGP型无线电探空仪可采集从地面至约30千米高度范围内的气压、气温、相对湿度、风速与风向数据。本数据集包含经厂商数据处理流程生成、并针对合理物理区间完成质量控制的1秒时间分辨率垂直廓线数据。
