NSF-MRI: Acquisition of a Microwave Radiometer for Arctic Atmospheric Boundary Layer Research & Education

该奖项全部或部分由2021年美国救援计划法案（公法117 - 2）资助。该主要研究仪器奖用于购买微波辐射计，以加强高纬度大气边界层（ABL）研究和空气污染气象学，中尺度建模和低空云-ABL相互作用的应用领域。该仪器将提高阿拉斯加大学费尔班克斯的研究能力，使其成为空气污染和人类健康的重要课题，与ABL动态和空气质量有关。该工具还将被用作教育工具，供包括阿拉斯加土著人和代表性不足的少数民族在内的各种本科生和研究生群体使用，他们来到阿拉斯加寻求以北极为重点的研究和教育机会。研究团队将从RPG Radiometer Physics购买RPG-HATPRO-G5，这是最新一代的微波辐射计，具有增强的低湿度大气能力。该小组将把微波辐射计纳入阿拉斯加大学费尔班克斯大气科学系现有的北极大气遥感设施，并将与激光雷达和地面湍流仪器相结合。还将准备将该仪器部署到一个移动的装置中进行实地研究。该仪器的获取将增强研究课题，包括：a）提高对地面通量和大气边界层动态的理解; B）在地面温度逆温的建立和破裂期间提供大气边界层结构的高分辨率描述; c）提高对升高的天气温度逆温层和地面逆温之间的动力-辐射相互作用的理解; d）提供冬季大气边界层结构的实验观测，以支持国际全球大气化学-阿拉斯加分层污染和化学分析（IGAC-ALPACA）; e）支持详细描述夏季ABL结构的火灾天气应用，f）改进可再生能源应用的中尺度建模，g）支持教育项目，包括关注北极的动态气象学。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

This award is funded in whole or in part under the American Rescue Plan Act of 2021 (Public Law 117-2).This Major Research Instrumentation award is for the acquisition of a Microwave Radiometer to enhance high-latitude Atmospheric Boundary Layer (ABL) research and applied areas of Air Pollution Meteorology, Mesoscale Modeling and Low Level Cloud-ABL interaction. This instrument will enhance the research capabilities at the University of Alaska Fairbanks into important topics for Air Pollution and Human Health, connected to the ABL dynamics and Air Quality. The instrument will also be used as an educational tool for use by a diverse cohort of undergraduate and graduate students including Alaskan Natives and underrepresented minority groups coming to Alaska seeking for an Arctic-focused research and education opportunity. The research team will acquire the RPG-HATPRO-G5 from RPG Radiometer Physics, which is the latest generation of microwave radiometers with enhanced capability for low humidity atmospheres. The team will incorporate the Microwave Radiometer into the existing Arctic Facility for Atmospheric Remote Sensing at the Department of Atmospheric Sciences, University of Alaska Fairbanks and will be combined with Lidar and surface-based turbulence instrumentation. The instrument will also be prepared to be deployed into a mobile unit for field studies. Topics of study that will be enhanced by this instrument acquisition includes: a) improve understanding of surface fluxes and ABL dynamic states; b) provide high resolution description of the ABL structure during the buildup and breakup of surface based temperature inversions; c) improve understanding of dynamic-radiative interaction between elevated synoptic temperature inversions layers and the surface based inversions; d) provide experimental observations of the winter ABL structure to support the International Global Atmospheric Chemistry - Alaskan Layered Pollution and Chemical Analysis (IGAC-ALPACA); e) support Fire Weather applications detailing the summer ABL structure and f) improve mesoscale modeling for renewable energy applications and, g) support educational programs including dynamic meteorology with Arctic focus.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.
