Yang Li博士获奖项目介绍
贝勒大学环境科学助理教授, Yang Li 博士,荣获具有竞争力的 NASA 地球科学早期职业研究员计划奖。该计划旨在支持科学家和工程师在职业生涯早期的杰出科学研究和职业发展。她是贝勒环境科学领域第一位获得这一早期职业奖的教职。
Yang Li, Ph.D., assistant professor of environmental science at Baylor University, has won a competitive NASA Early Career Investigator Program in Earth Science award that supports outstanding scientific research and career development of scientists and engineers at the early stage of their professional careers. She is the first faculty member in environmental science to receive this early career award.
1、项目内容和优势
Li的创新研究项目——了解野火烟雾中的化学演化：在多尺度建模中利用遥感观测——与美国宇航局地球科学部门的优先事项相一致，包括增加天基遥感的使用，将天基遥感数据与其他数据相结合 数据集(例如地表、空气)并转化为模型并提供可操作的地球科学——使地球科学数据更有用、更有影响力，造福人类。
Li’s innovative research project –Understanding Evolving Chemistry in Wildfire Smoke: Leveraging Remote Sensing Observations in Multi-Scale Modeling – aligns with NASA’s Earth Science Division priorities, including increasing the use of space-based remote sensing, integrating space-based remote sensing data with other datasets (e.g., surface, air) and into models and delivering actionable Earth science – making Earth science data more usable and impactful for the benefit of humanity.
“得知获得这个奖项我很兴奋。我认为美国宇航局的及时支持将为我的实验室带来更多与火灾相关的研究机会，我们为潘多尼亚全球网络开发的遥感产品也将使全球大气界受益, ”Li 说到, “此外，我想说这个奖项很大程度上反映了我的部门、学院和大学的大力支持，我对此表示非常感谢。”
“I was excited to learn that I received this award. I think this timely support from NASA will open more fire-related research opportunities in my lab, and our developed remote sensing products for the Pandonia Global Network will also benefit the atmospheric community globally,” Li said. “Also, I want to say this award greatly reflects the strong support from my department, college and university, which I really appreciate.”
2、研究的重要性和必要性
考虑到野火对气候变化的重要性日益增加，Li 将她的研究主题描述为“相关、及时且重要”，对于了解大气成分和“前瞻性思维”。她的研究将着眼于更频繁的野火烟雾的洲内和洲际运输事件，这些事件通过显着提高顺风城市上空烟雾污染物的环境水平，对公众健康造成紧迫威胁。Li 说，根据气候变化预测，野火烟雾的远距离影响可能会进一步加剧。然而，她指出，人们对羽流化学反应如何影响运输过程中微量气体和气溶胶的成分缺乏了解，这主要是由于当前监测网络的测量不足，并且缺乏准确的模型来表示野火羽流的复杂的垂直结构。
Li described her research topic as “relevant, timely [and] significant” for understanding atmospheric composition and “forward-thinking” considering the increasing importance of wildfires with climate change. Her research will look at the intra- and inter-continental transport events of more frequent wildfire smoke that cause a pressing threat to public health by significantly enhancing ambient levels of smoke pollutants over downwind cities. The long-distance consequences of wildfire smoke could be further exacerbated according to climate change predictions, Li said. However, she noted a significant lack of understanding of how in-plume chemical reactions influence the composition of trace gases and aerosols along the transport processes, primarily due to insufficient measurements from current monitoring networks and lack of accurate modeling to represent the complex vertical structures of wildfire plumes.
“这项研究将利用遥感观测来更好地约束三维大气模型，”Li 说。“这将使我们能够利用地面网络的模型结果和产品来支持对流层排放的验证：污染监测（TEMPO）观测，通过提供对不断变化的化学、紫外线气溶胶观测和标准痕量气体产品的深入解释，从而增强 使用 TEMPO 数据集来解释美国的长期空气质量。”
“This research will leverage remote sensing observations to better constrain a three-dimensional atmospheric modeling,” Li said. “This will allow us to use model results and products from ground networks to support validation of Tropospheric Emissions: Monitoring of POllution (TEMPO) observations by providing in-depth interpretation of evolving chemistry, UV aerosol observations and standard trace gas products, thereby enhancing the usage of TEMPO datasets to interpret air quality in the U.S. in the long term.”
Yang Li 博士背景及研究介绍
Li 作为一名密歇根大学博士毕业生，她加入贝勒大学和哈佛大学环境科学系，担任博士后研究员，从事甲烷卫星和甲烷空气数据分析和科学应用工作，重点研究温室气体通量反演。她在哈佛大学的其他研究项目主要是使用耦合建模框架来调查未来气候、植被和土地利用实践的变化对粉尘流动和野火活动的影响。
A Ph.D. graduate of the University of Michigan, Li joined Baylor and the environmental science faculty from Harvard University, where she was a Postdoc Fellow working on MethaneSAT and MethaneAIR data analysis and science applications, with a focus on greenhouse gas flux inversion. Her other research projects at Harvard centered on using a coupled modeling framework to investigate the impacts of future changes in climate, vegetation and land use practices on dust mobilization and wildfire activity.
在密歇根大学期间，Li 应用并开发了大涡模拟模型和区域化学输运模型来解释生物挥发性有机化合物的垂直分布。在密歇根州，她还进行了一个冰川项目，调查气溶胶沉积对格陵兰冰盖融雪的影响。Li 的研究兴趣涵盖微量气体和气溶胶的当地大气化学模型到气候和空气质量协同效益的全球解释。在贝勒，她领导着Li 研究小组，该小组为本科生、研究生以及博士后研究人员提供空气质量和气候方面的研究机会。
While at Michigan, Li applied and developed a large-eddy simulation model and regional chemical transport models to interpret the vertical distribution of biogenic volatile organic compounds. At Michigan, she also did a glacial project investigating the impact of aerosol deposition on snowmelt over the Greenland Ice Sheet. Li’s research interests span from local atmospheric chemistry modeling of trace gases and aerosols to global interpretation of climate and air quality co-benefits. At Baylor, she leads the Li Research Group, which offers research opportunities on air quality and climate for undergraduate and graduate students as well as postdoctoral researchers.
“早期职业奖明确表明资助机构看到了研究人员巨大的长期潜力，”环境科学教授兼主席乔治·科布博士说。“Li 博士获得的 NASA 奖项是贝勒大学环境科学系的首个奖项，应该成为Li博士、她的学生和同事未来许多研究机会的基础。”
“Early Career Awards represent a clear indication that funding agencies see the significant long-term potential of researchers,” said George Cobb, Ph.D., professor and chair of environmental science. “Dr. Li’s NASA award is a first for the Environmental Science Department at Baylor University and should serve as the foundation for many future research opportunities for Dr. Li, her students and her colleagues.”
