A three-year program of comprehensive studies of ionospheric E- and F-region electrodynamics and of related aeronomic issues surrounding meteor-derived metals in the upper atmosphere is proposed. The proposed studies are based on an extensive ongoing observing program at Arecibo Observatory (AO) that involves incoherent scatter radar (ISR) and meteor-mode radar as well as proposed associated metal (Ca/Ca+, Fe, K, Na) lidar observations. AO is uniquely suited for these proposed studies with the new dual-beam capability yielding the first true 3-D observations, extreme sensitivity and directivity in both ISR and meteor-modes, and the common-volume lidar capabilities. The proposed observational and theoretical studies are intended to comprehensively test and extend the hypotheses and conclusions concerning the origin and scale of the apparently "new" electrodynamic processes resulting plasma-sheets and related phenomena including true sporadic-E and in firmly tying micrometeoroid atmospheric-entry processes to the aeronomy of metals in the upper atmosphere and to provide whole-earth micrometeoroid mass fluxes of unprecedented accuracy.

提出了一项为期三年的计划，全面研究电离层 E 区和 F 区电动力学以及高层大气中流星衍生金属的相关航空问题。 拟议的研究基于阿雷西博天文台（AO）正在进行的广泛观测计划，其中涉及非相干散射雷达（ISR）和流星模式雷达以及拟议的相关金属（Ca / Ca +，Fe，K，Na）激光雷达观测。 AO 非常适合这些拟议的研究，其新的双光束功能可实现首次真正的 3D 观测、ISR 和流星模式下的极高灵敏度和方向性，以及普通体积激光雷达功能。 拟议的观测和理论研究旨在全面测试和扩展有关明显“新”电动过程的起源和规模的假设和结论，该过程产生等离子体片和相关现象，包括真正的零星E和牢固束缚的微流星体进入大气层处理高层大气中金属的航空学，并提供前所未有的精确度的全地球微流星体质量通量。
