This project will investigate the dynamic and electrodynamic interactions between upper atmospheric regions using measurements acquired by an extensive suite of ground-based instrumentation located throughout the Caribbean. Specifically, the research will focus on characterizing the development of neutral and electrodynamic irregularities related to sporadic, patchy layer formation in the lower (E-region) ionosphere, traveling ionospheric disturbances, and quasi-periodic irregularities associated with coupling between the ionospheric E- and F-regions. Experimental investigation of these phenomena will utilize the incoherent scatter radar at Arecibo, Puerto Rico, in addition to active and passive optical remote sensing by Arecibo imagers and LIDAR systems. Active experiments using the new Arecibo facility for ionospheric modification are also planned. To supplement the Arecibo instrumentation, a set of coherent scatter radar imagers, one located on St. Croix and one to be deployed on the island of Dominica in the West Indies as part of the proposed work, will be used to locate plasma irregularities, identify their intermediate-scale structuring, and place them in the context of quantitative, ground-based measurements for the first time. This project will result in a significant expansion of ground-based infrastructure in the Caribbean which will benefit both students and international collaborators.

该项目将利用遍布加勒比地区的大量地面仪器获得的测量结果来研究高层大气区域之间的动态和电动相互作用。 具体来说，该研究将侧重于表征与电离层下部（E区）零星、斑片层形成相关的中性和电动不规则性的发展、行进电离层扰动以及与电离层E和电离层之间的耦合相关的准周期性不规则性。 F区。 对这些现象的实验研究将利用波多黎各阿雷西博的非相干散射雷达，以及阿雷西博成像仪和激光雷达系统的主动和被动光学遥感。 还计划使用新的阿雷西博设施进行电离层修改的积极实验。 为了补充阿雷西博仪器，一套相干散射雷达成像仪（一个位于圣克罗伊岛，一个将部署在西印度群岛的多米尼加岛，作为拟议工作的一部分）将用于定位等离子体不规则性，识别它们的中尺度结构，并首次将它们置于定量的地面测量的背景下。 该项目将显着扩大加勒比地区的地面基础设施，这将使学生和国际合作者受益。
