This award provides funding to advance fundamental understanding of urban processes as a function of land surface properties, atmospheric chemistry, and human adaptive choices designed to reduce impacts of storms and heatwaves over urban areas. The study will focus on Chicago, New York, and Denver regions that vary in geography, climatology, urban characteristics, and urbanization processes. The resulting improvement in the understanding of urban processes is ultimately expected to improve the quality of life for vulnerable urban communities impacted by more frequent and extreme storms and heatwaves events. This project will help evaluate the impact of green infrastructure choices and future urban expansion. The use of satellite datasets for storm and heatwave characterization, data assimilation, and validation will ensure portability to other urbanized areas across the world with limited in-situ and radar observations as well as cities with similar climatic conditions. The project will disseminate project findings through peer-reviewed publications and presentations at conferences and workshops, webinars to citizens and city administrators, and social media for global reach. The project will train a postdoc and two graduate students to be next-generation atmospheric scientists with interdisciplinary expertise in climate model development, hydrometeorological data analysis, and urban sustainability. This project will utilize a combination of numerical model development activities, model enhancements, and new measurement techniques from space and the earth’s surface to characterize the nonlinear effects of land cover, urban morphology, geometry, scale, and aerosol heterogeneity on the urban boundary layer processes impacting storms and heatwaves. This project will contribute to the following objectives: (i) analyze the effects of interactions between the atmosphere and intra-urban land surface properties and characteristics on storms and heatwaves, (ii) analyze the contribution of urban aerosols on storms and heatwaves, and (iii) analyze the impacts of changing urban landscapes due to human development and adaptation choices. The project will also articulate atmospheric chemistry interactions due to urban aerosol heterogeneity and intra-urban land surface processes related to convergence and convection that modify storms and heatwaves. The weather-chemistry linkages using new model development activities and model enhancements will likely improve weather forecasting capabilities for cities. Project techniques and resulting findings will also serve as a new paradigm for integrated studies for sustainable and resilient urban systems, especially in evaluating how future urbanization and urban climate change adaptation strategies like green and cool roofs will impact storms and heatwaves over urban areas.This collaborative project is co-funded by the Physical and Dynamic Meteorology and Environmental Sustainability programs.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该奖项提供了资金，以促进对城市过程的基本了解，这是土地表面特性，大气化学和人类适应性选择的函数，旨在减少城市地区风暴和热浪的影响。该研究将重点关注芝加哥，纽约和丹佛地区，这些地区的地理，气候学，城市特征和城市化过程各不相同。最终，人们最终会改善对城市进程的理解，这将改善受到更频繁和极端风暴和热浪事件影响的脆弱城市社区的生活质量。该项目将有助于评估绿色基础设施选择和未来城市扩张的影响。使用卫星数据集用于风暴和热波表征，数据同化和验证，将确保对世界其他城市化地区的便携性，其现场和雷达观察有限，以及具有相似文化条件的城市。该项目将通过在会议和研讨会上进行同行评审的出版物和演示，向公民和城市管理员进行网络研讨会以及全球范围的社交媒体来传播项目调查结果。该项目将培训一个博士后和两名研究生，成为下一代大气科学家，在气候模型开发，水文学数据分析和城市可持续性方面具有跨学科专业知识。该项目将利用数值模型开发活动，模型增强功能以​​及从太空和地球表面的新测量技术的组合来表征土地覆盖，城市形态，几何形态，规模和气溶胶异质性对影响风暴和热门的城市边界过程的非线性影响。该项目将有助于以下目标：（i）分析大气与城市内陆地表面特性和特征对暴风雨和热浪的特征，（ii）分析城市气溶胶对风暴和热浪的贡献，以及（iii）分析因改变人类开发和适应性选择而导致的城市景观的影响。该项目还将由于城市气溶胶异质性以及与收敛和转化有关的城市气溶胶异质性和城市内陆地表面过程而阐明大气化学的相互作用，从而改变了风暴和热浪。使用新的模型开发活动和模型增强功能的天气化学联系可能会改善城市的天气预测能力。项目技术和结果发现也将成为用于可持续和抵抗城市系统整合研究的新范式使用基金会的智力优点和更广泛的影响标准，认为通过评估被认为是宝贵的支持。
