MRI-Acquisition: Puerto Rico Atmospheric Major Research Laser Instrumentation Program (PR-LASER)

研究人员将为阿雷西博天文台的钾多普勒共振激光雷达获得最先进的激光发射器。这将取代目前的发射机，该发射机已有近15年的历史，难以维护。升级的目的是：1)利用阿雷西博的新激光技术加强上层大气研究活动；2)提高数据质量、系统可靠性，增加科学家、工程师、研究生和本科生使用现代研究仪器的机会和培训；3)实施科学、技术、科学和科学领域的研究培训计划。光学工程和数学（STEM）领域，重点是大气遥感，面向大学预科到研究生院的学生和来自波多黎各大都会大学波多黎各光学科学研究所（PROptScI）的科学教师。激光雷达性能的改进将提高其测量钾密度和温度的准确性和精度，并最终实现对中间层和低层热层（MLT）风的测量。当与电离层雷达相结合时，改进的激光雷达将导致全天候测量MLT的温度和风，以及白天的大气密度。此次收购将在阿雷西博天文台和一所以西班牙裔为主的大学之间创造新的协同效应。UMET的本科生将有机会参与并学习使用最先进的电光技术进行中大气研究的细节。这些学生将在他们选择的职业中成为领导者，因为这种伙伴关系提供了独特的机会。UMET将与CRRL/CTC合作开发激光雷达技术，并培训将成为下一代激光雷达科学家的本科生和研究生。

The investigators will acquire a state-of-the-art laser transmitter for the potassium Doppler resonance lidar at the Arecibo Observatory. This will replace the current transmitter, which is almost 15 years old and is difficult to maintain. The purpose of the upgrade is to 1) enhance upper-mesospheric research activities using new laser technology at Arecibo, 2) improve data quality, system reliability, and increased access to and training in the use of modern research instrumentation by scientists, engineers, and graduate and undergraduate students, and 3) implement a research training program in science, technology, engineering and mathematics (STEM) fields in optics with an emphasis on atmospheric remote sensing for students from pre-college through graduate school and science teachers from Puerto Rico at Universidad Metropolitana's Puerto Rico Optical Sciences Institute (PROptScI). The improved performance of the lidar will enhance the accuracy and precision of its measurements of potassium density and temperature and ultimately enable the measurement of winds in the mesosphere and lower thermosphere (MLT). When coupled with the ionospheric radar, the improved lidar will lead to around-the-clock measurements of MLT temperatures and winds, and daytime atmospheric air densities. The acquisition will create new synergy between the Arecibo Observatory and a majority-Hispanic university. Undergraduates from UMET will have the opportunity to participate in and learn the details of middle atmosphere research using state-of-the-art electro-optic technologies. These students will become leaders in their chosen careers because of the unique opportunities presented by this partnership. UMET will partner with the CRRL/CTC to develop lidar technologies and train undergraduate and graduate students who will be the next generation of lidar scientists.
