This project involves post-processing of original field data collected as part of the Deep Convective Clouds and Chemistry Study (DC3) conducted in May and June of 2012. The primary goal of the DC3 campaign was to determine the influence of deep, midlatitude continental convective clouds, including related dynamical, physical, and lightning processes, on upper tropospheric/lower stratospheric (UT/LS) composition and chemistry. In the UT/LS, formaldehyde and peroxides are major sources of ozone. Careful analyses of the DC3 dataset are important for understanding and interpreting radical production in the UT/LS due to convective transport of precursors that influence the production of ozone. Data from the DC3 campaign will increase the understanding of the atmospheric chemistry and dynamics related to the formation of ozone in the upper troposphere, where ozone acts as a greenhouse gas. Detailed analysis of campaign data will help elucidate possible mechanisms that occur during deep convection and plume aging that influence water vapor, ozone, cirrus cloud and aerosol concentrations that all play important roles in contributing to radiative forcing of the Earth's climate system.

该项目涉及对 2012 年 5 月和 6 月进行的深对流云和化学研究 (DC3) 中收集的原始现场数据进行后处理。DC3 活动的主要目标是确定深中纬度大陆对流的影响云，包括对流层上层/平流层下层 (UT/LS) 成分和化学的相关动态、物理和闪电过程。在 UT/LS 中，甲醛和过氧化物是臭氧的主要来源。由于前体对流传输影响臭氧的产生，对 DC3 数据集的仔细分析对于理解和解释 UT/LS 中自由基的产生非常重要。 DC3 活动的数据将增进对与对流层上层臭氧形成相关的大气化学和动力学的了解，臭氧在对流层上层充当温室气体的作用。 对活动数据的详细分析将有助于阐明深对流和羽流老化期间发生的可能机制，这些机制会影响水蒸气、臭氧、卷云和气溶胶浓度，而这些都在地球气候系统的辐射强迫中发挥着重要作用。
