有机气溶胶（OA）作为冰核粒子（INPs）在大气中的丰度很高，值得关注。INPs的低浓度给在环境中多种气溶胶类型中识别OA的冰成核（in）带来了挑战。本研究将催化汽提器系统（350°C加热）与连续流动扩散室相结合，在线研究了郊区站点环境颗粒在- 30°C下的浸泡INPs。蒸发后INP浓度显著降低（71±25%），表明挥发性OA对INP的贡献显著。此外，非挥发性OA比黑碳是更有效的INPs。光氧化氧化的OA和较低的环境在中午促进了OA的IN活性，此时OA可能更粘稠。因此，这些结果提供了第一个现场证据，表明在人为影响区域的OA可以是有效的INPs，远高于均匀的INPs温度。
The role of organic aerosols (OA) as ice nucleating particles (INPs) deserves attention because of their high atmospheric abundance. The low concentration of INPs poses challenges in identifying the ice nucleation (IN) of OA among a mix of aerosol types in ambient environment. This study coupled a catalytic stripper system (350°C heating) with a continuous flow diffusion chamber to online investigate the immersion INPs of ambient particles at −30°C at a suburban site. Significant reduction (71 ± 25%) of INP concentrations after evaporation suggested that INPs can be significantly contributed by volatile OA. In addition, nonvolatile OA were more efficient INPs than black carbon. Oxygenated OA by photooxidation and lower ambient promoted the IN activity at noon, when the OA may be more viscous. These results hereby present the first field evidence that OA in anthropogenically influenced regions can be efficient INPs well above the homogeneous IN temperature.
