摘要
在大气模型中要正确呈现气溶胶 - 云相互作用，就需要冰核粒子（INP）的排放速率和特性。很少有研究对海洋INP排放进行量化，而海洋对于偏远海洋区域来说是一个潜在的重要INP来源。先前的研究表明，海雾气溶胶（SSA）中的INP与海洋生物活动有关。在本研究中，通过在两次围隔实验期间测量浮游植物大量繁殖时新生SSA的INP排放，对这种假定的联系进行了探究。在海洋气溶胶参考箱（MART）实验中，产生了浮游植物大量繁殖现象，叶绿素 - a（Chl a）浓度达到39微克/升，而在加利福尼亚大学圣地亚哥分校的波浪水槽中进行的海洋粒子化学与传输科学调查（IMPACTS；叶绿素 - a峰值为5微克/升）活动期间，获得了更能代表自然海洋条件的叶绿素 - a浓度。INP排放出现了动态趋势……
AbstractEmission rates and properties of ice nucleating particles (INPs) are required for proper representation of aerosol–cloud interactions in atmospheric models. Few investigations have quantified marine INP emissions, a potentially important INP source for remote oceanic regions. Previous studies have suggested INPs in sea spray aerosol (SSA) are linked to oceanic biological activity. This proposed link was explored in this study by measuring INP emissions from nascent SSA during phytoplankton blooms during two mesocosm experiments. In a Marine Aerosol Reference Tank (MART) experiment, a phytoplankton bloom was produced with chlorophyll-a (Chl a) concentrations reaching 39 μg L−1, while Chl a concentrations more representative of natural ocean conditions were obtained during the Investigation into Marine Particle Chemistry and Transfer Science (IMPACTS; peak Chl a of 5 μg L−1) campaign, conducted in the University of California, San Diego, wave flume. Dynamic trends in INP emissions occurred for INPs ...
