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.

这是一项为期三年的大气循环研究 对流层中的臭氧、活性氮和硫。 的 该项目将包括三个相关的调查重点， 全球对流层化学系统的具体方面， 目前还不太清楚， 区域和/或全球环境。 一项调查将 重点了解农村地区臭氧事件的成因 并将利用美国南部相当大的空气 南方氧化剂公司正在收集的质量数据库 Study. 第二次调查将旨在更好地 了解遥远的海盐气溶胶的化学性质 海洋大气及其对大气硫循环的影响 以及产生对气候重要的硫酸盐颗粒， 云凝结核 第三次调查将试图 阐明负责确定全球 活性氮化合物和臭氧的分布和丰度 通过应用三维全球化学 运输模型。 这最后一项研究将代表一个持续的 格鲁吉亚研究所的科学家们共同努力， 技术和NOAA的地球物理流体动力学实验室。
