Postprocessing and Data Analysis of Formaldehyde Measurements Aquired on the GV Aircraft During the 2012 Deep Convective Clouds and Chemistry Study

该项目包括对2012年5月和6月进行的深层对流云和化学研究（DC3）收集的原始野外数据进行后处理。DC3活动的主要目标是确定深层中纬度大陆对流云，包括相关的动力、物理和闪电过程，对对流层上层/平流层下层（UT/LS）组成和化学的影响。在UT/LS中，甲醛和过氧化物是臭氧的主要来源。对DC3数据集的仔细分析对于理解和解释UT/LS中由于影响臭氧产生的前体的对流输送而产生的自由基是很重要的。来自DC3活动的数据将增加对与对流层上层臭氧形成有关的大气化学和动力学的理解，在对流层上层臭氧是一种温室气体。对活动数据的详细分析将有助于阐明在深对流和羽流老化期间可能发生的机制，这些机制会影响水蒸气、臭氧、卷云和气溶胶浓度，而这些都在促进地球气候系统的辐射强迫方面发挥重要作用。

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.
