This is a three-year project to conduct an observation and data analysis effort centered on the incoherent scatter radar and optical facilities at the Arecibo Observatory. The scientific focus of the proposed study is gravity waves in the thermosphere over Arecibo, especially questions related to their detailed characteristics and origin. A special radar technique based on Photo-Electron Enhanced Plasma Waves (PEPW) as well as advanced analysis techniques developed by the proposing team will be utilized. These provide electron density measurements of unprecedented accuracy and allow for the identification of gravity waves in the radar observations at all times, day and night. In addition to collaboration with the radar staff at Arecibo, the proposal involves an extensive collaboration providing auxiliary data from imagers, lidars, and other instruments as well as widespread expertise on interpretation of these observations. Undergraduate and graduate student research opportunities will be provided as part of this proposal as well as other public outreach and educational activities at the Arecibo Observatory.

这是一个为期三年的项目，旨在进行观察和数据分析工作，该项目集中在Arecibo天文台的不连贯散点雷达和光学设施上。 拟议的研究的科学重点是热层上的重力波，尤其是与它们的详细特征和起源有关的问题。 将利用一种基于照片电子增强的血浆波（PEPW）以及提议团队开发的高级分析技术的特殊雷达技术。 它们提供了前所未有的精度的电子密度测量，并允许在任何时候，白天和黑夜都鉴定雷达观测中的重力波。 除了与Arecibo的雷达员工合作外，该提案还涉及广泛的合作，可提供来自成像器，激光雷达和其他工具的辅助数据，以及有关解释这些观察结果的广泛专业知识。 该提案的一部分以及Arecibo天文台的其他公共外展和教育活动将提供本科和研究生研究机会。
