气溶胶对气候和环境影响中心（CAICE）将解决阐明大气气溶胶颗粒的化学复杂性和反应性的重大挑战。CAICE的主要目标是更好地了解化学异质性，形态，相位和分子组成，在单个气溶胶颗粒水平，控制大气气溶胶的性质和反应性。需要详细的化学知识来预测气溶胶化学如何影响反应性、光吸收和散射行为以及云滴和冰晶的形成。一种全球重要的气溶胶类型，海喷雾，具有巨大的化学变化，取决于海洋化学，生物和物理条件，如波浪，风和太阳辐射。 CAICE利用独特的海洋-大气实验设施，将海洋和大气的真实、复杂化学直接带入实验室，在受控环境中复制自然海雾气溶胶转化。一个由来自各个领域的化学家，以及海洋生物学家，海洋学和大气科学家组成的跨学科团队将提供不同的观点和方法，以获得对气溶胶如何形成以及随后在大气中的行为的基本化学见解。将开发用于空间分辨化学分析的新实验工具，沿着开发用于分子水平和粗粒度模拟的新理论方法，以探索气溶胶颗粒的复杂性、异质性和动态方面，这些气溶胶颗粒跨越了广泛的长度和时间尺度。CAICE将推进广泛的科学学科，包括界面化学，空气质量和大气化学，成核，气候科学，多相和非均相反应过程，纳米颗粒特性和海洋地球化学。重要的社会效益包括：1）通过先进的模型，包括气溶胶对云和降水过程的影响，提高预测区域气候，大气化学和水资源的能力，以及2）下一代科学领导者的跨学科培训和教育，他们将为大规模环境系统开发解决方案。CAICE学生将站在基础化学的最前沿，同时解决与海洋，大气和气候相关的全球视角。所有CAICE参与者将接受培训，有效地将他们的科学发现传达给公众，创业，并在中心的教育和推广计划中发挥积极作用。这项研究将与加州大学圣地亚哥分校的桦树水族馆和其他公共场所密切合作，向公众传播。气溶胶对气候和环境影响中心是化学创新中心（CCI）计划的一部分。

The Center for Aerosol Impacts on Climate and the Environment (CAICE) will tackle the grand challenge of elucidating the chemical complexity and reactivity of atmospheric aerosol particles. The primary objective of CAICE is to better understand how chemical heterogeneity, morphology, phase, and molecular composition, at the individual aerosol particle level, control the properties and reactivity of atmospheric aerosols. Detailed chemical knowledge is needed to predict how aerosol chemistry influences reactivity, light absorption and scattering behavior, and cloud droplet and ice crystal formation. A globally important type of aerosol, sea spray, has tremendous chemical variability that depends on ocean chemistry, biology, and physical conditions such as waves, wind, and solar radiation. CAICE utilizes a unique experimental ocean-atmosphere facility to bring the real-world, complex chemistry of the ocean and atmosphere directly into the laboratory to replicate natural sea spray aerosol transformations in a controlled setting. An interdisciplinary team composed of chemists from all fields, as well as marine biologists, and oceanographic and atmospheric scientists will provide diverse perspectives and approaches to gain fundamental chemical insights into how aerosols form and subsequently behave in the atmosphere. New experimental tools for spatially-resolved chemical analysis along with new theoretical methodologies for molecular-level and coarse-grained simulations will be developed to explore the complex, heterogeneous, and dynamic aspects of aerosol particles bridging a broad range of length and time scales. CAICE will advance a wide range of scientific disciplines, including interfacial chemistry, air quality and atmospheric chemistry, nucleation, climate science, multiphase and heterogeneous reaction processes, nanoparticle properties, and ocean biogeochemistry. The important societal benefits include: 1) improved ability to predict regional climate, atmospheric chemistry, and water resources via advanced models that incorporate aerosol impacts on clouds and precipitation processes, and 2) the interdisciplinary training and education of the next generation of scientific leaders who will develop solutions for large scale environmental systems. CAICE students will be at the forefront of fundamental chemistry while addressing global perspectives related to the ocean, atmosphere, and climate. All CAICE participants will receive training in effectively conveying their scientific findings to the public, entrepreneurship, and play active roles in the Center's education and outreach programs. The research will be communicated to the public in close collaboration with the UC San Diego's Birch Aquarium and other public venues.The Center for Aerosol Impacts on Climate and the Environment is funded as part of the Centers for Chemical Innovation (CCI) program.
