This three-year study will investigate the inter-relationship between Polar Mesospheric Summer Echoes (PMSE) occurrence, mesospheric temperatures, mesospheric water vapor, and middle-atmosphere dynamics. Further, the PI will differentiate PMSE occurrence in the northern and southern hemispheres. The primary database for PMSE will derive from Poker Flat MST Radar data (northern hemisphere) and data from the Machu Picchu VHF radar located in Antarctica (southern hemisphere). These radars provide a reasonable latitude 'match.' In addition, he will use recent satellite water vapor measurements (HALOE) and middle-atmospheric wind and dynamics data from other high-southern-latitude (MF) radar sites. For the mesospheric temperatures, he will use all published data, new results from the Machu Picchu radar/rocket campaign (PORTA), and a meteor radar system at Machu Picchu to provide additional mesospheric wind and possibly temperature data.

这项为期三年的研究将调查极地中层夏季回波（PMSE）发生，中层温度，中层水汽和中层大气动力学之间的相互关系。 此外，PI将区分PMSE发生在北方和南半球。 PMSE的主要数据库将来自Poker Flat MST雷达数据（北方半球）和位于南极洲的马丘比丘甚高频雷达（南半球）的数据。 这些雷达提供了一个合理的纬度匹配。此外，他还将使用最近的卫星水汽测量（HALOE）和来自其他高南纬度（MF）雷达站点的中层大气风和动力学数据。 对于中间层温度，他将使用所有公布的数据、马丘比丘雷达/火箭活动的新结果以及马丘比丘的流星雷达系统，以提供更多的中间层风和可能的温度数据。
