Collaborative Research: Modeling and Data Analysis of the Tropospheric Ozone Production about the Spring Equinox (TOPSE) Experiment

这个项目是一个控制北美洲北方中高纬度地区氧化剂浓度过程的模拟研究。 一套1-D，区域3-D和全球3-D模式将被用来分析在春分实验（TOPSE）对流层臭氧生产过程中收集的空中观测。 研究的主要科学问题包括：（1）春季O_3最大值的纬度和高度分布及其影响因素：（2）O_3、NOx、NO_y、CO和碳氢化合物的时纬相关性及其对春季O_3最大值的起源和HO_x、NOx来源的影响;（3）卤自由基对北极及邻近地区春季化学的影响。 这些研究将涉及评估输送和化学在该区域对流层化学中的相对作用。 王博士与刘永强合作，格鲁吉亚理工学院，ATM-0000338。

This project is a modeling study of processes that control the concentrations of oxidants at northern mid and high latitudes over North America. A suite of 1-D, regional 3-D, and global 3-D models will be used to analyze airborne observations collected during the Tropospheric Ozone Production about the Spring Equinox Experiment (TOPSE). Major scientific issues to be examined include: (1) the altitude and latitude distributions of the springtime O3 maximum and factors contributing to the variation in the spatial distributions; (2) the correlations among O3, NOx, NOy, CO, and hydrocarbons by time and latitude and their implications on the origin of the springtime O3 maximum and sources of HOx and NOx; (3) the impact of halogen radicals on chemistry in the Arctic and vicinity in spring. These studies will involve assessing the relative roles of transport and chemistry in the tropospheric chemistry of this region.
