海洋飞沫气溶胶的实验模拟

Laboratory simulation of sea spray aerosol

作为大气气溶胶的重要组成,海洋飞沫气溶胶(sea spray aerosol,SSA)在全球气候变化中发挥着重要作用.SSA的产生过程同时受到海洋和大气环境的共同作用,其理化性质和全球通量存在显著的区域性差异,进而导致目前SSA对全球环境和气候变化的贡献评估存在较大不确定性.为了认识SSA的形成过程以及不同环境要素对其产生的影响机制,目前已经展开了大量的研究工作,特别是在实验室受控条件下模拟SSA产生方面获得了丰富的研究成果.本文聚焦SSA实验室模拟研究,重点围绕SSA的产生、化学组成、物质转移以及其对不同环境因素响应方面的研究进展进行了系统总结,并展望了该领域未来的重点研究方向.

As an important component of atmospheric aerosol,sea spray aerosol(SSA)plays an important role in global climate change.The formation of SSA is affected by both marine and atmospheric environmental factors,leading to significant regional differences in its physical and chemical properties and global flux.This results in great uncertainties in the current assessment of the contribution of SSA to global environment and climate change.In order to understand the formation process of SSA and the impact mechanism of different environmental factors on it,several studies,especially in the simulation of SSA formation under controlled laboratory conditions,have been conducted.This review explores the laboratory simulation research of SSA,with focus on SSA formation related research progress,chemical composition,substance transfer and its response to different environmental factors.We make a systematic summary,and put forward further prospects for future key research directions.
