项目摘要

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.

气溶胶对气候和环境的影响（CAICE）将应对阐明大气气溶胶颗粒的化学复杂性和反应性的巨大挑战。 CAICE的主要目标是更好地了解化学异质性，形态，相和分子组成如何在单个气溶胶颗粒水平上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。全球重要的气溶胶，海上喷雾具有巨大的化学变异性，取决于海洋化学，生物学和物理状况，例如波浪，风和太阳辐射。 Caice利用独特的实验海洋大气设施将海洋和大气的复杂化学直接带入实验室，以在受控的环境中复制天然海洋喷雾剂的气溶胶转化。由来自各个领域的化学家以及海洋生物学家以及海洋学和大气科学家组成的跨学科团队将提供多种观点和方法，以获得基本的化学化学见解，以了解气溶胶以及随后在大气中的表现。将开发用于空间分辨化学分析的新实验工具，以及用于分子级和粗粒的新理论方法，以探索气溶胶颗粒的复杂，异质和动态方面，这些元素弥合了宽阔的长度和时间尺度。 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，多相和异质反应过程，纳米颗粒特性以及海洋生物地球化学。重要的社会益处包括：1）通过高级模型通过高级模型来预测区域气候，大气化学和水资源的能力，这些模型纳入了对云和降水过程的影响，以及2）下一代科学领导者的跨学科培训和教育，这些培训和教育将开发针对大型环境系统的解决方案。 Caice的学生将处于基本化学的最前沿，同时解决与海洋，氛围和气候有关的全球观点。所有CAICE参与者都将接受培训，以有效地将其科学发现向公众传达，企业家精神，并在中心的教育和外展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木水族馆和其他公共场所密切合作，向公众传达。气雾剂对气候和环境的影响中心作为化学创新中心（CCI）计划的一部分资助。
