实验室研究可以为环境气溶胶中单个颗粒尺度上发生的过程提供重要的见解。我们检查了单颗粒研究中气溶胶核心物理化学特性测量的准确性，并探讨了这些特性对环境气溶胶中发生的微观过程的影响。提出新的测量结果，我们在这里检查我们对气溶胶吸湿性、表面张力、粘度和光学特性的理解的改进，这些可以从复杂混合物的详细实验室测量到二次有机大气气溶胶的替代物中获得。
Laboratory studies can provide important insights into the processes that occur at the scale of individual particles in ambient aerosol. We examine the accuracies of measurements of core physicochemical properties of aerosols that can be made in single particle studies and explore the impact of these properties on the microscopic processes that occur in ambient aerosol. Presenting new measurements, we examine here the refinements in our understanding of aerosol hygroscopicity, surface tension, viscosity and optical properties that can be gained from detailed laboratory measurements for complex mixtures through to surrogates for secondary organic atmospheric aerosols.
