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.

提出了三年的电离层电子和F区域电动动力学以及围绕流星衍生金属的相关空气问题的综合研究计划。 拟议的研究基于Arecibo天文台（AO）的广泛观察程序，该计划涉及不连贯的散射雷达（ISR）和流星模式雷达以及拟议的相关金属（Ca/ca+，fe，fe，k，na）LiDAR观察。 AO非常适合这些提出的研究，具有新的双光束功能，可产生第一个真实的3D观测，ISR和流星模式中的极端灵敏度和方向性以及普通体积激光雷达的能力。 提出的观察和理论研究旨在全面测试和扩展有关显而易见的“新”电动力学过程的起源和规模的假设和结论，从而导致血浆表和相关现象及相关现象，包括真正的零星e，包括真正的零星，以及在牢固的氛围中，并为整个氛围提供了巨大的氛围，并为众多的氛围提供了众多的氛围。前所未有的准确性的通量。
