项目摘要
The investigators will develop an advanced, mobile, iron-resonance/Rayleigh/Mie Doppler lidar system to vertically profile temperatures, winds, meteoric iron densities, clouds and aerosols throughout the stratosphere, mesosphere and lower thermosphere. The proposed lidar integrates the state-of-the-art technologies of lasers, laser spectroscopy, electro-optics, and sensors into a single system to produce a powerful and robust tool with unmatched measurement capabilities. The revolutionary lidar design and the readiness of alexandrite laser technology make the Fe Doppler lidar superb in the following ways: it will be able to obtain simultaneous measurements of temperature (30-110 km), wind (80-110 km), Fe density (75-115 km), and aerosol (10-100 km) in both day and night with high accuracy, high precision, and high spatial and temporal resolutions. The lidar is robust and compact for groundbased mobile deployment. It is containerized to move via a truck or ship to field locations of interest with extensive geographic coverage. Chirp-free and dither-free frequency locking and saturation-free Fe layer resonance results in a bias-free estimate of winds and temperatures, which is revolutionary for Doppler lidar. High energy and the UV wavelength employed by the lidar leads to a much more sensitive estimate of temperature and aerosol backscatter in stratosphere and mesosphere than determined through Na and K lidars. The 80-cm multi-telescope receiver, double-etalon filter for high rejection of solar background, and a state-of-the-art diagnostic system ensures accurate measurements in both day and night. The resulting breakthrough in lidar technology will push the atmospheric observations to a completely new level and the mobility of the system will enable new scientific endeavors. The lidar will become a community tool, available to all scientific users. Partnerships with private sector companies will result in new products with wide scientific use and commercial impact. Innovative technologies developed in this project will lead to new applications of advanced laser and remote sensing technology in the detection of biological and chemical agents, in nano-scale tube engineering, and in semi-conductor inspection. Exceptional opportunities for graduate and undergraduate education and training will arise from this project. A large number of scientists have strong interests in the instrument development, spin-off applications, and the data collected by this lidar. Many of these scientists will educate and train graduate and undergraduate students for whom this instrument and its data will be essential. Minority and under-represented students will be recruited through the Woman in Engineering Office (WIE) and Research Experience for Undergraduates (REU). This project will support the research of a female scientist (PI).
调查人员将开发一种先进的、移动的、铁共振/瑞利/米氏多普勒激光雷达系统,以垂直描绘整个平流层、中间层和低热层的温度、风、流星铁密度、云和气溶胶。拟议的激光雷达将激光、激光光谱、光电和传感器的最新技术集成到一个系统中,以产生一个强大而强大的工具,具有无与伦比的测量能力。革命性的激光雷达设计和紫翠宝石激光技术的成熟,使铁多普勒激光雷达在以下方面表现出色:它将能够同时测量温度,(30-110公里),风(80-110 km),Fe密度(75-115 km)和气溶胶(10-100 km)的高精度、高精度和高时空分辨率。激光雷达是强大的和紧凑的地面移动的部署。它被集装箱化,通过卡车或船只运到地理覆盖范围广泛的感兴趣的实地地点。无啁啾、无抖动的频率锁定和无饱和的铁层共振导致无偏差的风和温度估计,这对多普勒激光雷达来说是革命性的。激光雷达采用的高能量和紫外波长导致对平流层和中间层的温度和气溶胶后向散射的估计比通过Na和K激光雷达确定的灵敏得多。80厘米的多望远镜接收器,双标准具过滤器,用于高抑制太阳背景,以及最先进的诊断系统,确保在白天和夜晚的准确测量。激光雷达技术的突破将把大气观测推向一个全新的水平,系统的移动性将使新的科学努力成为可能。 激光雷达将成为一个社区工具,供所有科学用户使用。与私营部门公司的伙伴关系将产生具有广泛科学用途和商业影响的新产品。该项目开发的创新技术将导致先进的激光和遥感技术在生物和化学制剂检测、纳米级管工程和半导体检测方面的新应用。研究生和本科教育和培训的特殊机会将从这个项目中产生。大量的科学家对该激光雷达的仪器开发、副产品应用和收集的数据都有浓厚的兴趣。这些科学家中的许多人将教育和培训研究生和本科生,对他们来说,这种仪器及其数据将是必不可少的。少数民族和代表性不足的学生将通过妇女在工程办公室(WIE)和本科生研究经验(REU)招募。该项目将支持一名女科学家的研究。
