Theoretical and Diagnostic Studies of Tropospheric Chemistry and the Atmospheric Cycles of Ozone, N, and S

这是一个为期三年的研究对流层中臭氧、活性氮和硫的大气循环的研究。该项目将包括三个有关的调查，重点是全球-对流层-化学系统的具体方面，这些方面目前了解甚少，但对区域和/或全球环境具有根本重要性。一项调查将集中于了解美国南部农村地区臭氧事件的起因，并将利用南部氧化剂研究正在收集的庞大的空气质量数据库。第二次调查将旨在更好地了解遥远海洋大气上的海盐气溶胶的化学性质及其对大气S循环的影响以及对气候重要的硫酸盐颗粒和云凝结核的产生。第三项研究将试图通过应用三维全球化学传输模型来阐明决定活性N化合物和臭氧的全球分布和丰度的过程。最后一项研究将代表佐治亚理工学院和NOAA地球物理流体动力学实验室科学家之间的持续合作努力。

This is a three-year research study of the atmospheric cycles of ozone, reactive nitrogen, and sulfur in the troposphere. The project will be comprised of three related investigations focussing on specific aspects of the global-tropospheric-chemical system that are presently poorly understood and are of fundamental importance to the regional and/or global environment. One investigation will focus on understanding the genesis of ozone episodes in rural areas of the southern United States and will make use of the sizeable air quality database that is being gathered by the Southern Oxidants Study. A second investigation will be aimed at better understanding the chemistry of sea salt aerosols over the remote marine atmosphere and their effect on the cycle of atmospheric S and the production of climatically important sulfate particles and cloud condensation nuclei. A third investigation will attempt to elucidate the processes responsible for determining the global distributions and abundance of reactive N compounds and ozone through the application a three-dimensional Global Chemical Transport Model. This last study will represent a continued collaborative effort between scientists at the Georgia Institute of Technology and NOAA's Geophysical Fluid Dynamics Laboratory.
