The PI seeks to explain the disagreement between motions inferred from analyzing incoherent scatter and partial reflection radar data, as measured during AIDA '89. Data sources come from the Arecibo UHF incoherent scatter radar and Utah State University imaging doppler interferometry MF radar. The PI will continue investigating: (1) scattering mechanisms involved, (2) whether IDI scattering points are turbulent eddies carried by the mean flow, (3) distribution of scattering points and their line of sight velocities in each 3km altitude range, and (4) whether ISR results are indicators of bulk motion, and whether the advection of temperature discontinuities is also subject to gravity wave influence.***

PI试图解释从分析AIDA '89期间测量的非相干散射和部分反射雷达数据推断出的运动之间的差异。数据来源来自阿雷西博超高频非相干散射雷达和犹他州立大学成像多普勒干涉测量中频雷达。PI将继续研究：(1)涉及的散射机制，(2)IDI散射点是否为平均气流携带的湍流涡流，(3)散射点在每3km高度范围内的分布及其视线速度，(4)ISR结果是否为体运动的指标，以及温度不连续的平流是否也受到重力波的影响
