This Community Instruments and Facilities (CIF) award makes the single-particle soot photometer (SP2) at Clemson University available to the broader atmospheric science community. The SP2 can be used to measure the mass of black carbon in individual aerosol particles suspended in air. In addition, the advanced capabilities of the SP2 allow direct measurement of black carbon mixing state, or the degree to which black carbon is mixed with other, non-incandescing chemical species, on a single-particle level. Funds awarded for this project will provide support to keep the SP2 in a user-ready state for laboratory studies, airborne field studies, and ground-based field deployments. The SP2 will be requestable by the scientific user community and provided with support to make full use of the soot photometer data. This project also supports outreach activities to reach a broader scientific community, to garner public interest in science, and to increase diversity in Science, Technology, Engineering and Math (STEM) disciplines.Black carbon or soot is an important aerosol type found in the atmosphere which is generated from nearly every combustion process, including vehicle engines, factories, and forest or agricultural fires. Soot aerosol is highly absorbing of sunlight, which makes it an important component to understanding local heating, micrometeorology, and long-range, long-term climate. Broader access to the SP2 instrument has the potential to advance knowledge in several topics concerning atmospheric aerosol particles. This award will enhance the ability of the broader scientific community to use the SP2 instrument at Clemson University 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.

这一社区仪器和设施(CIF)奖使克莱姆森大学的单粒子烟尘光度计(SP2)可供更广泛的大气科学界使用。SP2可以用来测量悬浮在空气中的单个气溶胶颗粒中的黑碳质量。此外，SP2的先进功能允许在单颗粒水平上直接测量黑碳的混合状态，即黑碳与其他非白炽化化学物质的混合程度。为该项目提供的资金将提供支持，使SP2处于可供用户使用的状态，以便进行实验室研究、机载现场研究和地面现场部署。科学用户社区将要求SP2，并向其提供支持，以充分利用烟尘光度计数据。该项目还支持开展外联活动，以便接触到更广泛的科学界，引起公众对科学的兴趣，并增加科学、技术、工程和数学(STEM)学科的多样性。黑碳或烟尘是大气中发现的一种重要的气溶胶类型，几乎由所有燃烧过程产生，包括车辆发动机、工厂和森林或农业火灾。烟尘气溶胶对太阳光的吸收能力很强，是了解局地加热、微气象和长期、长期气候的重要组成部分。更广泛地使用SP2仪器有可能促进有关大气气溶胶颗粒的几个专题的知识。该奖项将增强更广泛的科学界通过大气和地球空间科学设施和仪器申请流程使用克莱姆森大学SP2仪器的能力。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
