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.

该研究人员将在犹他州立大学大气与太空科学中心（CASS）的大气激光雷达天文台（ALO）升级雷利分散和共振激光雷达。升级包括探测器和数据采集系统，因此可以通过从平流层进入较低热层的两个激光膜系统进行科学观察。当前，有一个检测器和一个单通道数据采集系统。这些资金将用于购买针对LIDARS，数据采集系统的新探测器，以及用于控制数据采集和望远镜指向的软件。硬件和软件的这种结合将使ALO能够为雪松/定时科学目标提供中间气氛温度和风观测。雪松代表大气区域的耦合，能量和动力学，是一个全球变化程序，将理论建模与基于地面的测量结果结合在一起，以研究上层大气层和电离层。对于热层，电离层，中层能量和动力学，时间是NASA卫星计划，用于研究大气的相似区域。联合雪松/定时计划旨在协调基于地面和空间的观测值，以更好地理解较低热层和电离层中的物理过程。
