本文概述了美国宇航局大气层层析成像（ATom）的使命和迄今为止的科学发现的摘要。ATom是一项空中测量和建模活动，旨在表征太平洋、南部、大西洋和北冰洋最偏远地区对流层的组成和化学，并研究全球范围内人为和自然排放的影响。这些偏远地区主导着全球化学反应，对全球空气质量和气候异常重要。ATom数据提供了必要的现场测量，以了解化学物质及其反应的范围，并测试卫星遥感观测和远程大气大区域的全球模型。由于缺乏这些区域的数据，特别是海洋上的数据，我们对大气成分如何随着人为排放和物理气候变化而变化的理解受到限制。ATom被设计为一个全球规模的层析成像采样使命，具有广泛的地理和季节覆盖面，对流层垂直剖面，并详细的活性化合物和污染示踪剂的形态。ATom在2016年至2018年的四个季节中驾驶NASA DC-8研究飞机，在四个全球电路上收集了来自偏远对流层和平流层下部的气体，气溶胶和自由基物种的全面测量结果。在太平洋和大西洋海盆的长纬向剖面上，飞行保持了0.15-13公里高度的近乎连续的垂直剖面。对ATom数据的分析和建模导致了这里强调的重要早期发现。

This article provides an overview of the NASA Atmospheric Tomography (ATom) mission and a summary of selected scientific findings to date. ATom was an airborne measurements and modeling campaign aimed at characterizing the composition and chemistry of the troposphere over the most remote regions of the Pacific, Southern, Atlantic, and Arctic Oceans, and examining the impact of anthropogenic and natural emissions on a global scale. These remote regions dominate global chemical reactivity and are exceptionally important for global air quality and climate. ATom data provide the in situ measurements needed to understand the range of chemical species and their reactions, and to test satellite remote sensing observations and global models over large regions of the remote atmosphere. Lack of data in these regions, particularly over the oceans, has limited our understanding of how atmospheric composition is changing in response to shifting anthropogenic emissions and physical climate change. ATom was designed as a global-scale tomographic sampling mission with extensive geographic and seasonal coverage, tropospheric vertical profiling, and detailed speciation of reactive compounds and pollution tracers. ATom flew the NASA DC-8 research aircraft over four seasons to collect a comprehensive suite of measurements of gases, aerosols, and radical species from the remote troposphere and lower stratosphere on four global circuits from 2016 to 2018. Flights maintained near-continuous vertical profiling of 0.15–13-km altitudes on long meridional transects of the Pacific and Atlantic Ocean basins. Analysis and modeling of ATom data have led to the significant early findings highlighted here.
