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。该主要研究仪器奖是为了获得一台微波辐射计，以加强高纬度大气边界层（ABL）的研究和应用领域的空气污染气象学、中尺度模型和低空云-ABL相互作用。该仪器将加强阿拉斯加费尔班克斯大学对空气污染和人类健康等重要课题的研究能力，这些课题与ABL动力学和空气质量有关。该仪器还将被用作一种教育工具，供各种各样的本科生和研究生使用，包括阿拉斯加原住民和未被充分代表的少数群体，他们来到阿拉斯加寻求以北极为重点的研究和教育机会。研究小组将从RPG辐射计物理公司获得RPG- hatpro - g5，这是最新一代微波辐射计，具有增强的低湿度大气能力。该团队将把微波辐射计整合到阿拉斯加费尔班克斯大学大气科学系现有的北极大气遥感设施中，并将与激光雷达和地面湍流仪器相结合。该仪器还将准备部署到一个流动单位进行实地研究。此次仪器收购将加强的研究课题包括：a)提高对表面通量和ABL动态状态的理解；b)提供地表温度逆温形成和破裂过程中ABL结构的高分辨率描述；C)提高对高天气温度逆温层与地表逆温之间的动态辐射相互作用的认识；d)提供冬季ABL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)支持详细介绍夏季ABL结构的Fire Weather应用程序；f)改进可再生能源应用的中尺度建模；g)支持包括北极动态气象学在内的教育计划。该奖项反映了美国国家科学基金会的法定使命，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.
