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

该奖项是为合作研究项目提供支持的两个奖项之一。同伴奖授予佐治亚理工学院刘永强，ATM-0000338。该项目是对北美北部中高纬度地区控制氧化剂浓度的过程进行建模研究。一套1-D、区域3-D和全球3-D模型将用于分析春分实验（TOPSE）对流层臭氧产生期间收集的空中观测数据。研究的主要科学问题包括：(1)春季O3最大值的海拔和纬度分布及其空间变化的影响因素；(2) O3、NOx、NOy、CO和烃类在时间和纬度上的相关性及其对春季O3最大值和HOx、NOx来源的影响；(3)北极及附近地区春季卤素自由基对化学的影响。这些研究将包括评估运输和化学在该地区对流层化学中的相对作用。

This award is one of two made to provide support for a collaborative research project. The companion award is to Yongqiang Liu, Georgia Institute of Technology, 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.
