The PIs wish to determine the vertical transport of ice in clouds and the clouds' mechanism in controlling the concentration of water vapor in the upper troposphere. They will use a stable isotope method, and propose to simultaneously collect ice and vapor samples, as well as to gather supporting in situ thermodynamic, cloud physics, and satellite data. The project goal is to determine the formation altitude of ice in the tops of winter frontal and summer convective clouds and the relative role of cloud ice and vapor as a supplier of water vapor in the upper troposphere.

PIs希望确定冰在云中的垂直输送以及云控制对流层上层水汽浓度的机制。他们将使用稳定同位素方法，并建议同时收集冰和蒸汽样本，以及收集支持性的原位热力学、云物理和卫星数据。项目目标是确定冬季锋面云和夏季对流云顶部冰的形成高度，以及云冰和蒸汽作为对流层上层水蒸气供给者的相对作用。
