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.

这一重大研究仪器奖是为了表彰对紧凑型、便携式多普勒风激光雷达系统的收购。多普勒风激光雷达使用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的研究能力，使其成为公共安全和人类健康的重要主题，如雷暴和空气质量的引发。该仪器还将被用作教育工具，供多样化和服务不足的学生使用。研究团队将获得Halo Photonics Stream Line XR，这是一种脉冲多普勒测风雷达，具有人眼安全的激光、高脉冲率、低脉冲能量和相干外差探测。该团队将把激光雷达与现有仪器(如微波辐射计、雷达探测系统和地面仪器)整合在一起，以便它可以用于野外研究的移动配置或在校园的固定地点使用。此次收购将加强的研究课题包括：1)恶劣天气的对流起始和开始，2)湖泊和海风环流和沿海过程，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NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
