Mixing Thermodynamics in Atmospherically Relevant Organic Aerosol Systems

化学系的环境化学科学(ECS)计划和大气和地球空间科学系的大气化学(ATC)计划将支持卡内基梅隆大学的Neil Donahue教授和Allen Robinson教授的合作研究项目。教授们。多纳休和罗宾逊以及他们的学生将利用先进的质谱学技术来阐明不同大小和组成的气溶胶悬浮液的混合热力学和动力学。合作小组还将探索水在气溶胶形成和动态性质中的作用。这些结果还将为大气模式中有机气溶胶表示框架提供重要的输入。拟议的研究解决了气溶胶对气候模式预测的影响。这是当前气候模型中的主要不确定性之一。这项研究有可能改变我们对气候过程的理解。它将为希望在具有重要社会意义的尖端研究领域接受培训的学生提供极好的培训机会。

The Environmental Chemical Sciences (ECS) program of the Division of Chemistry and the Atmospheric Chemistry (ATC) program of the Division of Atmospheric and Geospace Sciences will support the collaborative research project of Prof. Neil Donahue and Prof. Allen Robinson of Carnegie Mellon University. Profs. Donahue and Robinson and their students will utilize advanced mass spectrometric techniques to elucidate mixing thermodynamics and kinetics of aerosol suspensions of varying size and composition. The collaborative team will also explore the role of water in the formation and dynamic nature of aerosols. The results will also provide vital input to a framework for organic-aerosol representation in atmospheric models.The proposed research addresses the impact of aerosols on climate model predictions. This is one of the main uncertainties in current climate models. The study has the potential to transform our understanding of climate processes. It will provide excellent training opportunities to students who wish to train in a cutting edge research field of great societal importance.
