Incoherent scatter radar (ISR) observations of the F-region at Arecibo, Puerto Rico, are used with simultaneous airglow observations of the [OI] 630 nm and 732 nm emissions at Arecibo and at El Leoncito, Argentina to study a variety of F-region irregularity phenomena. The primary purpose is to understand the formation and propagation of mesoscale traveling ionospheric disturbances. Because all-sky imagers at each site have sufficient sky coverage, magnetic conjugacy effects are also characterized. Rayleigh-Taylor instability driven plasma depletions are also witnessed at each site, and this study seeks to determine if these depletions commonly mirror between conjugate locations. In addition to the ISR and airglow diagnostics, both Defense Meteorological Satellite Program (DMSP) and Global Positioning Satellite (GPS) data are used to characterize the ionosphere near the southern Appleton anomaly and near the Arecibo conjugate point. The research is the focus of an Hispanic postdoctoral student, and includes significant international cooperation.

在波多黎各的阿雷西博，F-区域的非相干散射雷达（ISR）的观测，同时使用气辉观测的[OI] 630 nm和732 nm的排放在阿雷西博和在埃尔莱昂西托，阿根廷研究各种F-区域的不规则现象。主要目的是了解中尺度电离层行波扰动的形成和传播。 由于每个站点的全天空成像仪都有足够的天空覆盖范围，因此还描述了磁共轭效应。 瑞利-泰勒不稳定性驱动的等离子体损耗也见证了在每个网站，这项研究旨在确定这些损耗之间的共轭位置通常镜像。 除了ISR和气辉诊断，国防气象卫星计划（DMSP）和全球定位卫星（GPS）数据被用来描述电离层附近的南部阿普尔顿异常和附近的阿雷西博共轭点。 这项研究是西班牙裔博士后学生的重点，包括重要的国际合作。
