This project involves laboratory and field studies to help elucidate the chemical mechanisms underlying ozone production and hydroxyl radical reactivity in the atmosphere. This research includes intercomparison and development of instrumentation for measuring atmospheric free radicals, and studying the mixing ratios, loss rates and kinetics in urban, rural, and remote sites of the hydroxyl and the hydroperoxyl radicals. The project will investigate the source of observed and evening and nighttime signals of these radicals, as well as develop and deploy detection capabilities for atmospheric free radicals.

该项目涉及实验室和实地研究，以帮助阐明大气中臭氧产生和羟基自由基反应的化学机制。 这项研究包括测量大气自由基的仪器的相互比较和开发，以及研究城市、农村和偏远地区的羟基和过氧化氢自由基的混合比、损失率和动力学。 该项目将调查观察到的这些自由基的来源以及傍晚和夜间信号，并开发和部署大气自由基的检测能力。
