Collaborative Research: CEDAR--Planetary Scale Waves in the Ionosphere Using Arecibo and COSMIC

该项目将综合利用新的和现有的空间和地面数据，以确定大规模大气波驱动器能够改变低纬度电离层发电机以及随后整个电离层的运动和密度的机制和途径。将使用波多黎各的高精度阿雷西博非相干散射雷达直接观测波-电离层相互作用和垂直耦合区域，同时将使用COSMIC卫星电离层电子密度测量值、TIMED卫星风测量值和地面全球定位系统总电子含量测量值来确定观测所依据的行星尺度波的全球结构。分析的初始重点将使用在重大平流层变暖事件和强电离层波活动期间从这些平台获得的现有数据，作为项目的一部分，将从阿雷西博天文台获得新的ISR数据。这项工作将支持博士后研究人员和研究生的教育和研究培训，并涉及本科生的研究参与。这项合作是两所大学，国家大气研究中心和阿雷西博天文台之间的合作。

This project is to utilize a combination of new and existing space- and ground-based data to characterize the mechanisms and pathways by which large-scale atmospheric wave drivers are able to modify the low-latitude ionospheric dynamo and subsequent motion and density of the whole ionosphere. The region of wave-ionosphere interaction and vertical coupling will be observed directly using the highly precise Arecibo incoherent scatter radar (ISR) in Puerto Rico, while COSMIC satellite measurements of ionospheric electron density, TIMED satellite wind measurements, and ground-based GPS measurements of total electron content will be used to identify the global structure of planetary-scale waves that underlie the observations. An initial focus of the analysis will use existing data from these platforms acquired during a major stratospheric warming event and strong ionospheric wave activity, and new ISR data will be acquired from Arecibo Observatory as part of the project. This work will support the education and research training of a postdoctoral researcher and a graduate student as well as involve research participation by undergraduates. This collaborative effort is a partnership between two universities, the National Center for Atmospheric Research, and Arecibo Observatory.
