Continuation of Equatorial Mesospheric Studies Using a Meteor Echo Detection and Collection System

要了解能量在整个中层大气中的传输，需要在全球范围内进行观测。目前有许多观测项目在中高纬度地区提供这类信息。这个项目是利用圣诞岛VHF剖面仪上的流星回波继续研究赤道中间层。这些资料将分析平均风和潮汐气候学，以及大尺度波浪运动的结构和演变，以及它们与中间层半年振荡和对流层波型的关系。将在位于波纳佩、印度尼西亚和秘鲁的甚高频雷达上建造和安装额外的流星回波探测和收集系统。这些额外的台站将允许研究四个不同对流层气候区域的中间层动力学。* * *

To understand the transport of energy throughout the middle atmosphere requires observations around the globe. Many observational programs are currently in place providing such information at middle and high latitudes. This project is to continue studies of the equatorial mesosphere using meteor echo returns on VHF profilers on Christmas Island. These data will be analyzed for mean wind and tidal climatologies as well as the structure and evolution of large-scale wave motions and how they relate to the mesospheric semiannual oscillation and tropospheric wave patterns. Additional meteor echo detection and collection systems will be built and installed on VHF radars located in Pohnpei, Indonesia and Peru. These additional stations will allow study of mesospheric dynamics in four different tropospheric climatic regions. ***
