We propose a series of experiments in a cloud simulation chamber to investigate the inhibition of ice growth in cold cirrus clouds using the isotopic fractionation of water molecules during ice condensation as a novel tracer of microphysical processes. The development of the water isotope spectrometer and its application to investigate the inhibition of ice growth in simulated cirrus clouds is designed as a collaborative project between three experienced partners: PCI (Expertise: Laser/Molecular spectroscopy + TDL Sensors), Univ. Chicago (Atmospheric science and isotope research using airborne sensors) and KIT (Cloud experiments using the AIDA simulation chamber).

我们提出了一系列的实验，在云模拟室中的冰生长的抑制冷卷云使用的水分子的同位素分馏过程中的冰凝结作为一种新的示踪剂的微物理过程。水同位素光谱仪的开发及其在模拟卷云中研究冰生长抑制的应用是三个经验丰富的合作伙伴之间的合作项目：PCI（专业知识：激光/分子光谱学+ TDL传感器），芝加哥大学（使用机载传感器进行大气科学和同位素研究）和KIT（使用AIDA模拟室进行云实验）。
