项目摘要
The Environmental Chemical Sciences (ECS) program of the Division of Chemistry (NSF/CHE) and the Atmospheric Chemistry program of the Division of Atmospheric and Geospace sciences (AGS) will support the research project of Prof. Mitchio Okumura of California Institute of Technology (Caltech). Prof. Okumura and his students will employ Cavity Ringdown Spectroscopy (CRDS) to detect free radical intermediates formed during photooxidation of volatile organic compounds (VOCs). The project will contribute to our understanding of the chemical reactions that lead to photochemical smog and aerosol formation. Specific data and mechanisms will be provided for air quality models that form the scientific basis for policy decisions regulating anthropogenic emissions related to air pollution and climate change. The project will provide excellent training opportunities for graduate students in a research area of great societal importance and at the forefront of scientific research.
化学部(NSF/CHE)的环境化学科学(ECS)计划和大气和地球空间科学部(AGS)的大气化学计划将支持加州理工学院(Caltech)的Mitchio Okumura教授的研究项目。Okumura教授和他的学生将采用腔衰荡光谱(CRDS)来检测挥发性有机化合物(VOCs)光氧化过程中形成的自由基中间体。该项目将有助于我们了解导致光化学烟雾和气溶胶形成的化学反应。将为空气质量模型提供具体的数据和机制,这些模型构成管制与空气污染和气候变化有关的人为排放的政策决定的科学依据。 该项目将为研究生在具有重大社会意义的研究领域和科学研究的前沿提供极好的培训机会。
