Atmospheric aerosol properties inferred from their external mixing state

了解大气气溶胶的混合状态，即其中单个颗粒之间的差异，对于评估气溶胶对气候的影响至关重要。在这项研究中，我们进行了大气气溶胶测量，重点是粒子的吸湿性作为气溶胶混合状态的衡量标准，从而获得了粒子的吸湿性与其组成和云凝结核活动的关系的知识。我们还利用吸湿性数据评估了气溶胶粒子对云形成的贡献。这项研究的结果可以为今后对气溶胶混合状态的研究提供指导。

Understanding the mixing state of atmospheric aerosols, i.e., the differences among individual particles in them, is crucial for assessing the effect of aerosols on climate. In this study, we performed atmospheric aerosol measurements with a focus on particle hygroscopicity as a measure of the aerosol mixing state, thereby acquiring knowledge of the relationship of the particles' hygroscopicity to their composition and cloud condensation nucleus activity. We also assessed the contribution of aerosol particles to cloud formation by making use of the hygroscopicity data. The outcome of this study could serve as a guide for future studies on aerosol mixing states.
