Particle Hysteresis And Solidification Experiment : Optical and Nucleation Effects (PHASE-ONE)

美国国家科学基金会化学部的环境化学科学项目支持佛蒙特大学的朱塞佩·佩特鲁奇教授和斯科特·T。Martin博士将阐明生物源二次气溶胶（BSOA）的分子组成和相态之间的关系，以及对BSOA光学特性和云凝结核（CCN）活动的后续影响。这项研究将建立一个前所未有的了解分子水平的气溶胶特性和BSOA在调节地球的辐射平衡的作用之间的联系。通过将每个机构内已有的专门知识和研究基础设施汇集在一起而实现的协同增效作用将确保迅速推进对大气有机气溶胶这一关键方面的理解。以及将获得的基本数据将对整个大气科学界大有裨益。此外，合作研究和培训基础设施以及培训机会将得到显著加强，并为这一领域的未来发展奠定重要基础。

The Environmental Chemical Sciences Program in the Chemistry Division at the National Science Foundation supports the research of Professors Giuseppe Petrucci from the University of Vermont and Scot T. Martin from Harvard University who will elucidate the relationships between molecular composition and phase of biogenic secondary aerosols (BSOA) and the subsequent impact on BSOA optical properties and cloud condensation nuclei (CCN) activity. This research will build an unprecedented understanding of the link between molecular-level aerosol properties and the role of BSOA in regulating Earth's radiative balance. The synergism made possible by bringing together established expertise and research infrastructure within each institution would ensure rapid advance of the understanding of this critical aspect of atmospheric organic aerosol.The improved understanding of the complex interdependent relationships between chemical, phase and optical properties of organic aerosols, as well as the fundamental data that will be obtained will be of great benefit to the atmospheric sciences community at large. Furthermore, the collaborative research and training infrastructure as well as training opportunities, will be enhanced significantly and provide a critical foundation for future advances in this area.
