Upper air soundings during POLARSTERN cruise ANT-VIII/4

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，用于测量气压、温度、相对湿度和风矢量的垂直廓线。使用填充氦气的气球（TOTEX 600克、800克）携带维萨拉RS80无线电探空仪。在条件允许的情况下，施放时间约为世界协调时（UTC）10时。压缩测量数据（TEMP格式FM-35）被立即传输至全球电信系统（GTS），为全球天气预报提供支持。廓线数据每5-10秒采集一次，因此垂直廓线分辨率约为25-50米。廓线始于海拔10米的直升机甲板，终止于气球爆裂高度，通常在25至37千米之间。
