最近成立的国际全球大气化学（IGAC）南半球工作组的这篇评论论文概述了大气成分研究中特别影响南半球的关键问题。在本文中，我们对了解南半球大气化学的许多挑战进行了广泛的概述，然后将重点放在将南半球与北半球区分开来的最重要因素上。我们介绍了南半球生物源排放和火灾的重要性，表明在许多地区，这些排放往往占人为排放的主导地位。然后，我们描述了这些因素和其他因素如何影响南半球不同地区的空气质量。最后，我们描述了南大洋在影响大气化学方面的关键作用，并最后描述了新成立的IGAC南半球工作组的目标和范围。
This commentary paper from the recently formed International Global Atmospheric Chemistry (IGAC) Southern Hemisphere Working Group outlines key issues in atmospheric composition research that particularly impact the Southern Hemisphere. In this article, we present a broad overview of many of the challenges for understanding atmospheric chemistry in the Southern Hemisphere, before focusing in on the most significant factors that differentiate it from the Northern Hemisphere. We present sections on the importance of biogenic emissions and fires in the Southern Hemisphere, showing that these emissions often dominate over anthropogenic emissions in many regions. We then describe how these and other factors influence air quality in different parts of the Southern Hemisphere. Finally, we describe the key role of the Southern Ocean in influencing atmospheric chemistry and conclude with a description of the aims and scope of the newly formed IGAC Southern Hemisphere Working Group.
