Climatology of Meteor Winds over Atlanta (38 N, 84 W); August 1974 - April 1987

雷达提供了一个有用的方法来确定风在 通过在频率上的变化， 返回信号（多普勒频移），与 风速和高度定义的范围测量 雷达。 在夜间，电离层在下面大部分重新组合 在50至100公里的范围内没有散射体 区域，除了流星的电离尾巴。 （Meteors） 穿透大气层的视觉表现 行星间物质的微小碎片，大部分是 一粒或更小的沙子，偶尔有一个更大的， 大部分在入口处燃烧）。 流星雷达数据显示 潮汐、行星波、季节和太阳周期的存在 风的变化。 这个奖项是为了分析一个13年的集 将为CEDAR数据库编写，并提供给 一般来说，高层大气物理学社区，并用于生成 中层大气风的模型

Radars provide a useful means of determining winds in the upper atmosphere by means of the shift in frequency of the returned signal (the doppler shift) that is proportional to the wind speed and defined in altitude by the range measurement of the radar. At nighttime the ionosphere largely recombines below 100km and there is an absence of scatterers in the 50 to 100 km region, except for the ionized tails of meteors. (Meteors are the visual manifestation of the penetration into the atmosphere of tiny fragments of interplanetary material, mostly the size of a grain of sand or smaller, with occasionally a larger one, that mostly burn up on entry). The meteor radar data reveal the presence of tides, planetary waves, seasonal and solar cycle variations in winds. This award is for analysis of a 13 year set to be prepared for the CEDAR data base and made available to the Aeronomy community generally, and used in the generation of models of middle atmosphere winds.
