项目摘要

This investigators will upgrade Rayleigh scatter and resonance lidars at the Atmospheric Lidar Observatory (ALO) at the Center for Atmospheric and Space Sciences (CASS) at Utah State University. The upgrade includes detectors and a data acquisition system so that scientific observations can be made with the two lidar systems from the stratosphere into the lower thermosphere. Currently, there is one detector and a one-channel data acquisition system. The funds will be used to purchase new detectors for both lidars, a data acquisition system, and software for controlling the data acquisition and telescope pointing. This combination of hardware and software will enable ALO to contribute middle atmosphere temperature and wind observations in support of CEDAR/TIMED science goals. CEDAR, which stands for Coupling, Energetics, and Dynamics of Atmospheric Regions, is a global change program that combines theoretical modeling with ground-based measurements to study the upper atmosphere and ionosphere. TIMED, for Thermosphere, Ionosphere, Mesosphere Energetics and Dynamics, is a NASA satellite program to study similar regions of the atmosphere. The joint CEDAR/TIMED program aims to coordinate ground-based and space-based observations to achieve better understanding of physical processes in the lower thermosphere and ionosphere.

这项研究将升级犹他州州立大学大气和空间科学中心（卡斯）大气激光雷达观测站（ALO）的瑞利散射和共振激光雷达。这次升级包括探测器和数据采集系统，以便可以利用两个激光雷达系统从平流层到低热层进行科学观测。目前，有一个探测器和一个单通道数据采集系统。这笔资金将用于购买激光雷达的新探测器、数据采集系统以及控制数据采集和望远镜指向的软件。这种硬件和软件的结合将使ALO能够为支持CEDAR/TIMED的科学目标提供中层大气温度和风观测。 CEDAR代表耦合，能量学和大气区域动力学，是一个全球变化计划，将理论建模与地面测量相结合，以研究高层大气和电离层。 TIMED（Thermosphere，Ionosphere，Mesosphere Energetics and Dynamics）是美国国家航空航天局的一个卫星计划，用于研究类似的大气层区域。 CEDAR/TIMED联合方案旨在协调地面和空间观测，以更好地了解低热层和电离层的物理过程。
