Whether aerosols are internally (multicomponent) or externally (one component) mixed impacts aerosol-cloud interactions. The approach of this CAREER project centers on developing innovative modeling tools for quantifying the impact of per-particle (single) aerosol microphysical and chemical properties on aerosol-cloud interactions, on the micro to global scale. The work is motivated by growing observational evidence that shows tremendous variations in the chemistry and dynamics at a single-particle level. At present, however, the impacts of these variations are largely unquantified since in current regional or global models this complexity is not well-represented. This contributes to the large uncertainties in assessing the impact of aerosols on climate, limiting us from predicting the future impacts of air pollution on climate change.A comprehensive education and outreach plan that focuses on enhancing "climate literacy" along with the the recruitment of students into the STEM fields is integrated with this research. The educational program targets students and teachers at the middle-school level, students at the undergraduate and graduate levels, and the wider community.

气溶胶是内部（多组分）还是外部（单一组分）混合影响气溶胶-云相互作用。 这个CAREER项目的方法集中在开发创新的建模工具，用于量化每个粒子（单个）气溶胶微物理和化学特性对气溶胶-云相互作用的影响，在微观到全球尺度。这项工作的动机是越来越多的观测证据表明，在单粒子水平上，化学和动力学存在巨大的变化。 然而，目前，这些变化的影响在很大程度上没有量化，因为在目前的区域或全球模型中，这种复杂性没有得到很好的体现。 这导致了在评估气溶胶对气候的影响时存在很大的不确定性，限制了我们预测空气污染对气候变化的未来影响。本研究整合了一项全面的教育和推广计划，该计划沿着学生进入STEM领域，重点是提高“气候素养”。 该教育方案的目标是中学一级的学生和教师，本科生和研究生一级的学生以及更广泛的社区。
