Radar Studies of E and F Region Electrodynamics at Arecibo

该研究员正在阿雷西博天文台进行电离层E区和F区电动力学综合研究。 受到发现一种称为“离子雨”的电离层现象的启发，他正在测试和扩展有关这些“新”电动过程的起源和规模的假设，这些电动过程导致离子雨和相关现象，包括真正的零星E。 利用密集的非相干散射雷达观测、数值模拟和理论研究，他希望更好地理解作为关联的零星E、离子雨和扩展F事件观察到的明显小的水平尺度结构的起源和演变。 他的观测方法将证实或否认假设的小水平尺度电场结构的存在，这些电场结构沿着沿着基本上等势的地磁场线绘制，从而将E区和F区的电动力学与磁共枕点联系起来。 交互式的研究继续与实际的三维等离子体分布和漂移/E-场获得的数据。

The investigator is conducting comprehensive ionospheric E- and F-region electrodynamics studies at Arecibo Observatory. Inspired by discovering an ionospheric phenomenon termed 'ion rain,' he is testing and extending hypotheses about the origin and scale of these 'new' electrodynamic processes resulting in ion rain, and related phenomena, including true sporadic E. Using intensive incoherent scatter radar observations, numerical simulations and theoretical studies, he is hoping to better understand the origin and evolution of apparently small horizontal-scale structures observed as linked sporadic-E, ion rain, and spread-F events. His observational approaches will confirm or deny the existence of hypothesized small horizontal-scale electric field structures, mapped along the largely equipotential geomagnetic field lines, and thus connecting the electrodynamics of the E- and F-regions to the magnetic conjugate point. The studies are interactively continued with data obtained on actual three dimensional plasma distributions and drifts/E-fields.
