SGER: Peroxide Measurements during the Milagro Campaign

在Milagro现场活动期间，将在墨西哥城附近测量过氧化氢(过氧化氢、甲基过氧化氢和羟甲基过氧化氢)的丰度。这些物种是该地区预期的活跃光化学的主要终端产物，也是形成硫酸盐气溶胶的关键反应物。过氧化氢的测量将有助于米拉格罗运动的目标，即了解气相反应性的演变，特别是区域和全球范围内大气氧化潜力增加的可能性。此外，这些测量将有助于更好地了解气体-气溶胶相互作用。光化学和气溶胶模型被广泛用于了解人为和自然排放对地方、区域和全球的影响。改善这类模型的性能是一个主要目标，因为它们是探索各种缓解战略和潜在未来情景的影响的重要方法。这项工作将通过提供可用于验证和评估模型的活性物种的准确实验数据，对社会产生广泛的积极影响。

The abundance of hydroperoxides (hydrogen peroxide, methyl hydroperoxide, and hydroxymethyl hydroperoxide) will be measured near Mexico City during the MILAGRO field campaign. These species are principal end products of the active photochemistry expected in the region, and a key reactant in the formation of sulfate aerosol. Hydroperoxide measurements will contribute to the MILAGRO campaign goals of understanding the evolution of gas-phase reactivity, in particular the potential for increased atmospheric oxidation potential on a regional and global scale. In addition, these measurements will lead to a better understanding of gas-aerosol interactions. Photochemical and aerosol models are widely used to understand local, regional and global impacts of anthropogenic and natural emissions. Improved performance of such models is a major goal, as they are an important method to explore the effects of a variety of mitigation strategies and potential future scenarios. This work will have broad positive impacts on society by providing accurate experimental data on reactive species that can be used for validation and assessment of models.
