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天基和陆基数据，以确定大规模大气波驱动因素能够改变低纬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，同时将使用电离层电子密度的宇宙卫星测量、定时卫星风测量和总电子含量的地面全球定位系统测量，以确定观测所依据的行星尺度波的全球结构。分析的初步重点将使用在重大平流层变暖事件和强烈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。这项工作将支持一名博士后研究员和一名研究生的教育和研究培训，并让本科生参与研究。这项合作工作是两所大学--国家大气研究中心和阿雷西博天文台之间的合作伙伴关系。

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.
