Abstract Arctic aerosol-climate interactions are controlled by multiple factors including sources, processes and removal mechanisms of particles. The Arctic is mostly ocean, surrounded by mostly land, and our understanding of Arctic aerosol processes is incomplete due to scarce measurements carried out in sea ice regions. In particular, it is currently not known if these particular regions are sources of aerosols of primary or secondary origin. We present new results from ship-based measurements illustrating that marine new particle production and growth events occur in open ocean and melting sea ice regions in the Chukchi and East Siberian Seas. We report two new particle formation events during which a recently formed nucleation mode (

楚科奇和东西伯利亚海新粒子形成事件的北极船舶证据

摘要 北极气溶胶-气候相互作用受多种因素控制，包括颗粒的来源、过程和去除机制。北极大部分是海洋，周围大部分是陆地，由于在海冰区进行的测量很少，我们对北极气溶胶过程的了解是不完整的。特别是，目前尚不清楚这些特定区域是初级还是次级气溶胶的来源。我们提出了基于船舶的测量的新结果，表明海洋新粒子的产生和生长事件发生在楚科奇和东西伯利亚海的公海和融化的海冰区域。我们报告了两个新的粒子形成事件，其中最近形成的成核模式（
