This Small Business Technology Transfer (STTR) Phase II project will develop a compact cloud spectrometer and impactor (CSI) for the measurement and study of condensed water in the atmosphere. Condensed water includes cloud droplets and ice particles. Phase I demonstrated the feasibility of integrating a counterflow virtual impactor (CVI) for condensed water content (CWC) measurement together with a new forward scattering spectrometer system for measurement of the cloud droplet size distribution. This combined airborne instrument will be considerably lighter than previous versions of the two separate instruments, and easier to use. The objective of Phase II is a commercial, integrated instrument for the study of atmospheric condensed water content and droplet size distribution.The accurate measurement of these parameters is important in weather prediction as well as understanding global climate change. This instrumentation will have worldwide application, and the users will be government, university, and commercial atmospheric research institutions.

这个小型企业技术转让(STTR)第二阶段项目将开发一种紧凑型云光谱仪和撞击器(CSI)，用于测量和研究大气中的冷凝水。凝结水包括云滴和冰粒。第一阶段论证了将用于冷凝水含量测量的逆流虚拟冲击器(CVI)与用于测量云滴尺寸分布的新的前向散射光谱仪系统相结合的可行性。这种组合的机载仪器将比以前的两个单独的仪器版本要轻得多，并且更容易使用。第二阶段的目标是一个商业的综合仪器，用于研究大气凝结水含量和水滴尺寸分布。准确测量这些参数对于天气预报和了解全球气候变化非常重要。该仪器将在全球范围内应用，用户将是政府、大学和商业大气研究机构。
