MRI: Acquisition of a Portable Doppler Wind Lidar for Atmospheric Science Research and Education

该主要研究仪器奖是为了获得一种紧凑的便携式多普勒风激光雷达系统。多普勒风激光雷达使用一种人眼安全的激光来遥感大气边界层的特征，如风、湍流和气溶胶。该系统将增强路易斯安那大学门罗分校在公共安全和人类健康等重要课题上的研究能力，如雷暴的起源和空气质量。该仪器还将作为一种教育工具，供不同的和服务不足的学生群体使用。研究团队将获得Halo Photonics Stream Line XR，这是一种脉冲多普勒风激光雷达，具有人眼安全激光，高脉冲速率，低脉冲能量和相干外差检测。该团队将把激光雷达与现有的仪器（如微波辐射计、雷达探空系统和地面仪器）集成在一起，这样它就可以用于现场研究的移动配置，也可以用于校园的固定地点。此次收购将加强的研究课题包括：1)对流的开始和恶劣天气的发生，2)湖泊和海风环流和海岸过程，3)降水和云物理，以及4)气溶胶科学和空气污染。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 Major Research Instrumentation award is for the acquisition of a compact, portable Doppler Wind Lidar system. Doppler Wind Lidars use an eye-safe laser to remotely sense characteristics of the atmospheric boundary layer, such as wind, turbulence, and aerosols. This system will enhance the research capabilities at the University of Louisiana-Monroe into important topics for public safety and human health, such as the initiation of thunderstorms and air quality. The instrument will also be used as an educational tool for use by a diverse and under-served student population.The research team will acquire a Halo Photonics Stream Line XR, which is a pulsed Doppler Wind Lidar with an eye-safe laser, high pulse rate, low pulse energy, and coherent heterodyne detection. The team will incorporate the Lidar into a package with existing instrumentation such as a microwave radiometer, rawinsonde system, and surface instrumentation so it can be used in a mobile configuration for field studies or at a fixed-site location on campus. Topics of study that will be enhanced by the acquisition include: 1) Convective initiation and onset of severe weather, 2) Lake and sea breeze circulations and coastal processes, 3) Precipitation and cloud physics, and 4) Aerosol science and air pollution.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.
