项目摘要
This project is focused on establishing a fundamental understanding of the formation, processing, and fate of nitrogen compounds in the atmosphere. A series of laboratory chamber experiments will be performed to study the reactions of nitrogen compounds with volatile gases from biogenic sources. The results will lead to a better understanding of the formation of very small particles in the atmosphere that are relevant to air quality and climate.The objectives of the proposed research are to (1) To experimentally map out the effects of different environmental factors (humidity, temperature, particle acidity) on the formation of organic nitrate (ON) from biogenic volatile organic compounds (BVOC) and NO3; (2) To determine the changes in gas-particle partitioning and properties of ON with dark aging and photochemical aging; and (3) To characterize ON and the formation of secondary organic aerosol from BVOC+NO3 and assess their fates in a region of high BVOC/anthropogenic emissions.
该项目的重点是建立对大气中氮化合物的形成,加工和命运的基本理解。将进行一系列的实验室实验,以研究氮化合物与来自生物源的挥发性气体的反应。本研究的目的是(1)以实验方式研究不同环境因素对空气质量和气候的影响(湿度、温度、颗粒酸度)对生物源挥发性有机化合物(BVOC)和NO3形成有机硝酸盐(ON)的影响;(2)确定暗老化和光化学老化条件下ON的气粒分配和性质的变化;(3)表征ON和BVOC+NO3形成的二次有机气溶胶,并评估它们在高BVOC/人为排放区域的命运。
