Abstract

Aerosol and aqueous particles are ubiquitous in Earth's atmosphere and play key roles in geochemical processes such as natural chemical cycles, cloud and fog formation, air pollution, visibility, climate forcing, etc. The surface tension of atmospheric particles can affect their size distribution, condensational growth, evaporation, and exchange of chemicals with the atmosphere, which, in turn, are important in the above-mentioned geochemical processes. However, because measuring this quantity is challenging, its role in atmospheric processes was dismissed for decades. Over the last 15 years, this field of research has seen some tremendous developments and is rapidly evolving. This review presents the state-of-the-art of this subject focusing on the experimental approaches. It also presents a unique inventory of experimental adsorption isotherms for over 130 mixtures of organic compounds in water of relevance for model development and validation. Potential future areas of research seeking to better determine the surface tension of atmospheric particles, better constrain laboratory investigations, or better understand the role of surface tension in various atmospheric processes, are discussed. We hope that this review appeals not only to atmospheric scientists but also to researchers from other fields, who could help identify new approaches and solutions to the current challenges.

测量大气颗粒和相关混合物的表面张力,以便更好地了解关键的大气过程。
气溶胶和水颗粒在地球大气中无处不在,在地球化学过程中发挥着关键作用,如自然化学循环、云雾形成、空气污染、能见度、气候强迫等。大气颗粒物的表面张力会影响它们的大小分布、凝结生长、蒸发以及与大气的化学物质交换,进而在上述地球化学过程中发挥重要作用。然而,由于测量这一数量具有挑战性,几十年来它在大气过程中的作用一直被忽视。在过去的 15 年中,这一研究领域取得了巨大的发展,并在迅速演变。本综述介绍了这一课题的最新进展,重点是实验方法。它还介绍了 130 多种有机化合物混合物在水中的实验吸附等温线,对模型开发和验证具有重要意义。还讨论了未来可能的研究领域,以更好地确定大气颗粒的表面张力,更好地限制实验室研究,或更好地理解表面张力在各种大气过程中的作用。我们希望这篇综述不仅能吸引大气科学家,也能吸引其他领域的研究人员,帮助他们找到应对当前挑战的新方法和解决方案。
