对流层臭氧在地球大气化学过程中发挥着重要作用，也是一种空气污染物和温室气体。由于其寿命短，并且依赖于阳光和自然和人为来源的前体排放，对流层臭氧的丰度在季节、年际和年代际时间尺度上在空间和时间上具有很大的变化。观测到的臭氧混合比率和臭氧前体排放最近的、有时是快速的变化启发我们制作了这份对流层臭氧全球分布和趋势的最新概览。文本的大部分内容是同行评审文献中报告的现场和遥感臭氧观测的综合，但我们也包括一些新的和扩展的分析，使用众所周知的和参考的数据集，以得出臭氧趋势和世界不同区域分布之间的联系。此外，我们对三个最先进的化学气候模型计算的农村或偏远地表臭氧趋势的准确性进行了简要评估，这些模型是科学家用来填补我们对全球对流层臭氧分布和趋势知识空白的工具。
Tropospheric ozone plays a major role in Earth's atmospheric chemistry processes and also acts as an air pollutant and greenhouse gas. Due to its short lifetime, and dependence on sunlight and precursor emissions from natural and anthropogenic sources, tropospheric ozone's abundance is highly variable in space and time on seasonal, interannual and decadal time-scales. Recent, and sometimes rapid, changes in observed ozone mixing ratios and ozone precursor emissions inspired us to produce this up-to-date overview of tropospheric ozone's global distribution and trends. Much of the text is a synthesis of in situ and remotely sensed ozone observations reported in the peer-reviewed literature, but we also include some new and extended analyses using well-known and referenced datasets to draw connections between ozone trends and distributions in different regions of the world. In addition, we provide a brief evaluation of the accuracy of rural or remote surface ozone trends calculated by three state-of-the-science chemistry-climate models, the tools used by scientists to fill the gaps in our knowledge of global tropospheric ozone distribution and trends.
