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. Dr. Wang is collaborating with Yongqiang Liu, Georgia Institute of Technology, ATM-0000338.

这个项目是对北美北部、中纬度和高纬度地区控制氧化剂浓度的过程的模拟研究。一套一维、区域三维和全球三维模式将被用来分析在对流层臭氧产生期间收集的关于春分实验(TOPSE)的空中观测数据。将研究的主要科学问题包括：(1)春季臭氧最大值的海拔和纬度分布以及导致空间分布变化的因素；(2)臭氧、氮氧化物、氮氧化物、一氧化碳和碳氢化合物随时间和纬度的关系及其对春季臭氧最大值的来源和HOx和NOx的来源的影响；(3)卤素自由基对北极及其附近春季化学的影响。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。王博士正在与佐治亚理工学院的刘永强合作，ATM-0000338。
