Atmospheric aerosols are complex mixtures of different chemical species, and individual particles exist in many different shapes and morphologies. Together, these characteristics contribute to the aerosol mixing state. This review provides an overview of measurement techniques to probe aerosol mixing state, discusses how aerosol mixing state is represented in atmospheric models at different scales, and synthesizes our knowledge of aerosol mixing state's impact on climate‐relevant properties, such as cloud condensation and ice nucleating particle concentrations, and aerosol optical properties. We present these findings within a framework that defines aerosol mixing state along with appropriate mixing state metrics to quantify it. Future research directions are identified, with a focus on the need for integrating mixing state measurements and modeling.

气溶胶混合状态:测量,建模和影响

大气气溶胶是不同化学物种的复杂混合物,单个颗粒以许多不同的形状和形态存在。这些特性共同促进了气雾混合状态。这篇综述概述了探测气溶胶混合状态的测量技术,讨论了如何在不同规模的大气模型中表示气溶胶混合状态,并综合了我们对气溶胶混合状态对与气候相关的特性(如云凝结和冰核形成)的影响的知识。颗粒浓度和气溶胶光学特性。我们在定义气溶胶混合状态的框架内介绍了这些发现,并结合了适当的混合状态度量对其进行了量化。确定了未来的研究方向,
