CAREER: A Comprehensive Investigation into Cloud-Aerosol Interactions Using Satellite, Aircraft and Model Data

这一职业项目将云物理、气溶胶科学和气候变化领域的最先进研究与新颖的教学工具、社区教育和推广以及改进气象学本科生和研究生教育计划结合在一起。对气溶胶对云和降水的影响(通过修改云层)的知识不足，导致气溶胶对整体气候影响的量化存在很大不确定性，并导致对全球气候模型的预测不佳。将通过三个创新研究主题分析气溶胶-云相互作用，以满足这些需要：(1)利用A-Train卫星数据集，遥感研究气溶胶对云和降水的直接、间接和半直接影响；(2)利用A-Train卫星数据集，对混合过程进行观测研究，并根据云的大小、寿命、气溶胶类型和地面特征调查气溶胶-云相互作用；和(3)利用并置的A-Train卫星观测对云-气溶胶相互作用进行模式评估，以确定观测结果与全球气候模型之间的不一致之处，以指导全球气候模型的未来发展和改进。通过利用三种截然不同的数据类型，该项目能够在各种空间尺度(单个云到全球尺度)和时间尺度(云中的微秒到年平均值)上分析气溶胶-云相互作用。这项研究使用的各种平台也将为研究生研究人员提供特别广泛的背景和不同的技能集。上述研究与本项目的教育目标密切相关。关于云、气溶胶和气候的最新研究将整合到本科课程中，以提高对这一热门媒体话题的整体科学素养。采用利用多媒体教学技术(即YouTube和播客)的小组课堂活动将鼓励学生通过课程材料确定“现实世界”当前天气事件和气候问题之间的联系。此外，一个创新的本科生研究生指导计划将指导本科生，同时发展研究生的监督和指导技能，因为他们开始了上述概述的研究。该研究项目还将通过为研究生和本科生提供在著名研究机构实习并与精英科学家合作的机会，促进夏威夷大学和NASA喷气推进实验室之间的合作。为了广泛地影响社区，PI将在夏威夷组织一年一度的扩大您的视野(EYH)会议(该州的第一次会议)。该协会将招募当地的夏威夷女科学家和行业领袖，目标是教育和吸引年轻女性进入STEM领域。作为EYH会议的一部分，国际和平研究所将使用通过所述研究工作收集的数据主办实践讲习班。

This CAREER project merges state-of-the art research in the fields of cloud physics, aerosol science and climate change with novel instructional tools, community education and outreach, and improvement of undergraduate and graduate education initiatives in meteorology. Insufficient knowledge of aerosol effects on clouds and precipitation (via cloud modification) causes a large uncertainty in quantification of the overall climatic effects of aerosols and results in poor predictions on global climate models. These needs will be addressed through the analysis of aerosol-cloud interactions via three innovative research themes: (i) Remote sensing studies on the impact of aerosols on clouds and precipitation via the direct, indirect and semi-direct effects using A-Train Satellite data sets; (ii) Observational studies on mixing processes with investigations into aerosol-cloud interactions based on cloud size, lifetime and aerosol type and surface characteristics; and (iii) Model Evaluation of cloud-aerosol interactions using collocated A-Train Satellite observations to identify inconsistencies between observations and global climate models to guide future development and improvement in global climate models.By utilizing three distinctly different data types this project allows for the analysis of aerosol-cloud interactions on a variety of spatial (individual clouds to global scale) and temporal scales (micro-seconds in cloud to yearly means). The variety of platforms used for this study will also provide graduate student researchers with an exceptionally broad background and varied skill set.The research described above is closely intertwined with the education goals of this project. State-of-the-art research on clouds, aerosols and climate will be integrated into undergraduate courses to increase the overall scientific literacy of a "hot" media topic. The adoption of group class activities utilizing multi-media teaching techniques (i.e. YouTube and Podcasts) will encourage students to identify connections between the "real world" current weather events and climate issues with course material. Additionally, an innovative undergraduate-graduate student mentoring program will guide undergraduates while simultaneously developing supervising and mentoring skills in graduate students as they embark on the research outlined above. The research program will also foster collaborations between the University of Hawaii and NASA's Jet Propulsion Laboratory by providing graduate and undergraduate students the opportunity to intern and work with elite scientists at a renowned research facility. To broadly impact the community the PI will organize an annual Expanding Your Horizon (EYH) conference in Hawaii (the first for that state). The PI will recruit local Hawaiian women scientists and industry leaders with the goal of educating and attracting young women to the STEM fields. As part of the EYH conference the PI will sponsor hands-on workshops using data collected through the described research efforts.
