引入了一种新的科学有效载荷，用于对气象（风矢量、静态空气温度、湿度和气压）和微物理（气溶胶粒子和云滴）特性进行精细测量，该有效载荷悬挂在系留气球下方。介绍了高分辨率传感器和系留气球。本文介绍了第一次实地考察中的一个雾层的观测结果，对雾/霾和逆温层的详细研究表明，雾对温度波动有阻尼作用，而逆温层的发展使风的波动明显减弱，根据光谱分析，高分辨率传感器的本底噪声为10 ~（-6）kg·m ~（-3）（液态水含量）和4 mK的快速温度传感器（UFT-B）。本文研究了浅霾层中LWC结构与温度的关系。潜热的释放和相应的变暖的阴霾约0.1 K可以量化。
A new scientific payload is introduced for fine-scale measurements of meteorological (wind vector, static air temperature, humidity, and air pressure) and microphysical (aerosol particles and cloud droplets) properties, suspended below a tethered balloon. The high resolution sensors and the tethered balloon are described. Measurements in a lifted fog layer from a first field campaign are presented.The detailed investigation of the fog/haze and the temperature inversion layer demonstrates the damping influence of the fog on temperature fluctuations, while thewind fluctuations are significantly decreased by theevolving temperature inversion, whichwas about 30 m above the fog layer.From spectral analysis the noise floors of the high-resolution sensors are determined to10-6 kg m-3 for the LWC (liquid water content) and 4 mK for the fast temperature sensor (UFT-B). The correlation betweentemperature and LWC structures in shallow haze layers is investigated. The release of latent heat and the corresponding warming in the haze of about 0.1 K could be quantified.
