This project will build and fly on balloons instruments for measuring the size and other characteristics of particles found in the arctic stratosphere. These condensation nuclei (CN) and polar stratospheric cloud (PSC) particles play an important role in the destruction of ozone by catalytic action of chlorine. The balloon measurements will be made at the same time as nitric acid (HNO3) vapor measurements will be made by another team from Max Planck Institute, Heidelberg, Germany. Nitric acid is one of the main constituents of the PSC particles. This work is important to increasing understanding of the processes which cause the annual springtime decreases of ozone in both polar regions, and also to help understand the differences between the Arctic and Antarctic stratosphere.

该项目将建立和飞行在气球仪器上，以测量北极平流层中发现的颗粒的大小和其他特征。 这些冷凝核（CN）和极性平流层云（PSC）颗粒在通过氯的催化作用破坏臭氧中起着重要作用。 气球测量将与硝酸（HNO3）蒸气测量同时进行，将由德国海德堡的Max Planck Institute的另一个团队进行。 硝酸是PSC颗粒的主要成分之一。 这项工作对于增加对两个极地区域春季春季减少的过程的理解非常重要，也可以帮助理解北极和南极平流层之间的差异。
