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.

该奖项的全部或部分资金来源于《2021 年美国救援计划法案》（公法 117-2）。该重大研究仪器奖项用于购买微波辐射计，以加强高纬度大气边界层 (ABL) 研究以及空气污染气象学、中尺度建模和低层云与 ABL 相互作用的应用领域。该仪器将增强阿拉斯加大学费尔班克斯分校对空气污染和人类健康重要主题的研究能力，这些主题与 ABL 动力学和空气质量相关。该工具还将用作教育工具，供各类本科生和研究生使用，其中包括阿拉斯加原住民和前往阿拉斯加寻求以北极为重点的研究和教育机会的少数族裔群体。研究团队将购买 RPG RadiometerPhysics 的 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。该团队将把微波辐射计整合到阿拉斯加大学费尔班克斯分校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基湍流仪器相结合。该仪器还将准备部署到移动装置中进行现场研究。通过购买该仪器将加强的研究主题包括： a) 提高对表面通量和 ABL 动态的理解； b) 在基于地表的温度反演的建立和分解过程中提供 ABL 结构的高分辨率描述； c) 增进对天气温度逆温层升高和地表逆温之间动态辐射相互作用的理解； 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) 支持教育计划，包括以北极为重点的动态气象学。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力优点和更广泛的影响审查标准进行评估，被认为值得支持。
