CIF: Making the Pi Convection-Cloud Chamber Available to the Community for Aerosol-Cloud-Turbulence Research

这个社区仪器和设施（CIF）奖是为了支持密歇根理工大学的Pi对流云室。该项目将使Pi对流云室和一套广泛的支持仪器可供大气科学界用于调查包括气溶胶和云在内的大气过程。Pi对流云室设计用于模拟大气层下部（对流层）压力和温度范围内的云条件。它是北美唯一一个用于研究的大型实验室云室。该奖项还将通过商会实验室奖学金计划为访问学生提供为期10周的体验式学习计划，并扩大学生对物理科学的参与。Pi对流云室在气溶胶-云相互作用、冰成核和混合相云特性、云光学特性和湿瑞利-贝纳德对流方面具有良好的记录。 Pi Chamber和配套仪器构成了一个测量大气科学研究中热力学、湍流、气溶胶和云特性的设施。该奖项将提高更广泛的科学界通过大气和地球空间科学设施申请流程申请和使用Pi云室进行研究的能力。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

This Community Instruments and Facilities (CIF) award is for support of the Pi Convection-Cloud Chamber at Michigan Technological University. This project will make the Pi Convection-Cloud Chamber and an extensive set of supporting instrumentation available to the atmospheric sciences community for investigations of atmospheric processes that include aerosols and clouds. The Pi Convection-Cloud Chamber is designed to simulate cloud conditions within the range of pressures and temperatures that occur in the lower part of the atmosphere (the troposphere). It is the only operating major laboratory cloud chamber for research use in North America. The award will also support a 10-week experiential learning program for visiting students through a Chamber laboratory fellowship program and broaden student participation in the physical sciences. The Pi Convection-Cloud Chamber has a proven record of enabling productive and insightful research in aerosol-cloud interactions, ice nucleation and mixed-phase cloud properties, cloud optical properties, and moist Rayleigh-Bénard convection. The Pi Chamber and supporting instruments make a facility that enables measurement of thermodynamics, turbulence, aerosol, and cloud properties for research in the atmospheric sciences. This award will enhance the ability of the broader scientific community to request and use the Pi Cloud Chamber for research through the Atmospheric and Geospace Sciences facility 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.
