This Community Instruments and Facilities (CIF) award makes the North Carolina State ice nucleation Cold Stage (NC State CS) freezing assay available as a community instrument facility. The instrument consists of a machine vision optical system to observe a thermally controlled surface. The main purpose of the instrument is to observe the freezing nucleation process of supercooled water droplets. The instrument is suitable for studying ambient ice nucleating particle concentrations and laboratory-based process-level studies of the nucleation process. The facility will be advertised at conferences, including conferences that exclusively target professional societies focused on fostering enhanced diversity in science. Interactive educational content will be created and disseminated using a multi-user web-interface that can be used by instructors to supplement instruction in a wide range of undergraduate and graduate courses.This project contributes instrumentation and educational resources to tackle the problem of characterizing the abundance of ice nucleating particles in the atmosphere. By becoming a community instrument facility, the cold-stage technique will become more widely available to groups that do not specialize in instrument design. Funds for the award will also yield a public design of a low-cost version of the instrument that can be self-manufactured. This award will enhance the ability of the broader scientific community to use the NC State ice nucleation cold stage freezing assay through the Atmospheric and Geospace Sciences facility and instrument request process.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该社区工具和设施（CIF）奖使北卡罗来纳州冰核阶段（NC State CS）冻结了作为社区仪器设施的冻结测定法。该仪器由机器视觉光学系统组成，以观察热控制的表面。该仪器的主要目的是观察超冷水滴的冻结成核过程。该仪器适合研究核定过程的环境冰核浓度和基于实验室的过程水平研究。该设施将在会议上进行宣传，其中包括专门针对专业社会的会议，旨在促进发展科学的多样性。将使用多用户网络接口创建和传播互动教育内容，教师可以使用该互动教育内容来补充各种本科和研究生课程。该项目贡献了仪器和教育资源，以解决特征丰富的问题​​的问题大气中的冰核颗粒的粒子。通过成为社区仪器设施，冷阶段技术将成为不专门从事仪器设计的团体的广泛使用。该奖项的资金还将产生可以自行制造的低成本版本的公共设计。该奖项将增强更广泛的科学界使用NC州ICE成核通过大气和地理水平科学设施和仪器请求过程使用NC状态冰核冰冻测定法。该奖项反映了NSF的法定任务，并被认为是通过使用评估的支持值得的。基金会的智力优点和更广泛的影响审查标准。
