Upper air soundings during POLARSTERN cruise ARK-XIX/1

The upper air soundings are normally performed once a day to measure vertical profiles of air pressure, temperature, relative humidity and the wind vector. Helium filled balloons (TOTEX 600 g, 800 g) were used to carry Vaisala RS80 radiosondes. Whenever possible, the launches were performed about 10 UTC. Condensed measurements (TEMP Format FM-35) were transferred without delay into the Global Telecommunication System GTS were they contribute for the world wide weather forecasts. The profile data were taken every 5-10 seconds which result in a vertical profile resolution of about 25-50 meter. The profiles start at the helideck 10 m above sea level and terminate at the burst level of the balloons, normally at heights between 25 and 37 km.

高空探测通常每日进行一次，旨在测量气压、温度、相对湿度和风向的垂直分布。本次实验采用了填充氦气的气球（TOTEX 600 g，800 g），以携带 Vaisala RS80 无线电探空仪。在可能的情况下，探测发射时间约为 10 UTC。浓缩测量数据（TEMP 格式 FM-35）被即时传输至全球电信系统 GTS，为全球天气预报提供数据支持。垂直剖面数据每 5-10 秒采集一次，从而实现了约 25-50 米的垂直分辨率。剖面数据从海平面以上 10 米的直升机甲板开始，至气球破裂高度结束，通常位于 25 至 37 公里的高度范围内。
