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.

使用波多黎各阿雷西博F区的非相干散射雷达(ISR)观测和阿雷西博和阿根廷El Leoncito的气辉同时观测[OI]630 nm和732 nm发射，研究各种F区不规则性现象。主要目的是了解中尺度行进电离层扰动的形成和传播。因为每个地点的全天成像仪都有足够的天空覆盖率，所以磁共轭效应也是典型的。瑞利-泰勒不稳定性导致的等离子体耗尽也出现在每个位置，这项研究试图确定这些耗尽是否通常反映在共轭位置之间。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)数据都被用来描述阿普尔顿南部异常附近和阿雷西博共轭点附近的电离层。这项研究是一名西班牙裔博士后的重点，其中包括重大的国际合作。
