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.

在MILAGRO实地活动期间，将在墨西哥城附近测量氢过氧化物（过氧化氢、甲基氢过氧化物和羟甲基氢过氧化物）的丰度。 这些物种是该地区预期的活跃光化学的主要最终产物，也是形成硫酸盐气溶胶的关键反应物。 氢过氧化物测量将有助于实现MILAGRO活动的目标，即了解气相反应性的演变，特别是在区域和全球范围内增加大气氧化潜力的潜力。 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。 提高这些模型的性能是一个主要目标，因为它们是探索各种减缓战略和未来潜在情景的重要方法。 这项工作将对社会产生广泛的积极影响，提供准确的实验数据，反应物种，可用于验证和评估模型。
