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.

研究者正在Arecibo天文台进行全面的电离层电子和F区电动力学研究。 通过发现一种被称为“离子降雨”的电离层现象的启发，他正在测试并扩展有关这些“新”电型动力学过程的起源和规模的假设，导致离子降雨和相关现象，包括真正的零星E.，包括使用强烈的散布散射雷达观察，数字和理解的频率，他的频繁的频率和理解的是，他的原始散布和理解的频率较小，以至于他的频繁良好的水平，以至于启发了起来的范围。观察到链接的零星，离子雨和传播F事件。 他的观察方法将确认或否认存在假设的小水平尺度电场结构，并沿着很大程度上的地磁磁场线映射，从而将电子和F区域的电动力学连接到磁性共轭点。 通过在实际三维等离子体分布和漂移/电子场上获得的数据进行交互作用。
