Over the past 10 years, a chain of 12 atmospheric/meteor radars has been constructed that stretches from the Antarctic to the Arctic through North and South America. I am principal investigator on 5, share a sixth, and collaborate with other scientists on another 6. Others exist world-wide. These radars all have a common heritage, scientifically designed by me. They measure winds and temperatures between 80 and 100 km altitude, and I am still developing even more applications. This spread represents the broadest latitudinal coverage and highest latitudinal density of any single type of middle atmosphere radar. I am currently integrating all the data from these facilities into a common web site at which all these data are displayed and updated every few hours, facilitating interactions between the radar owners and other researchers world-wide. The web site, and the ensuing collaborative science that is resulting, represents the first time that middle atmosphere meteorology has been displayed for general user access in near-real-time on such a frequent and world-wide scale. This system will allow unique new perspectives on global studies of upper atmospheric dynamics, comparable in latitudinal coverage to many satellites, and superior to all satellites in regard to temporal coverage and vertical resolution. When combined with several other VHF windprofiler radars that I operate in Canada, including in the Arctic, the system makes a powerful national and international major facility for studies of atmospheric processes at 80 to 100 km altitude. The proposed program of research will capitalize on this unique capability. Studies will include wind and temperature investigations of planetary wave, tidal and gravity wave oscillations, studies of momentum flux and divergence, wind forcing, vertical winds, turbulence strengths and microsctructure, radar scattering mechanisms, effects of enhanced Carbon Dioxide in the upper atmosphere, and meteor/space-debris physics, among others. The network has already been employed to assist with NASA Space Shuttle re-entries. With 46 refereed publications in the last 6 years, I have proven my capability to successfully employ these networks, and look forward to achieving their full potential.

在过去的10年里，已经建造了12个大气/流星雷达链，从南极延伸到北极，穿过北美和南美。我是5个项目的首席研究员，分享第6个项目，并与其他科学家合作完成另外6个项目。其他的存在于世界各地。这些雷达都有一个共同的遗产，由我科学地设计。它们测量海拔80到100公里之间的风和温度，我还在开发更多的应用。这一分布代表了任何单一类型的中层大气雷达的最宽的纬向覆盖范围和最高的纬向密度。目前，我正在将这些设施的所有数据整合到一个共同的网站上，每隔几个小时就会在这个网站上显示和更新所有这些数据，以促进雷达所有者和世界各地其他研究人员之间的互动。这个网站，以及随之而来的科学合作成果，代表了中层大气气象学第一次以如此频繁和全球范围的近实时方式向普通用户展示。该系统将为高层大气动力学的全球研究提供独特的新视角，在纬度覆盖范围上可与许多卫星相媲美，在时间覆盖范围和垂直分辨率上优于所有卫星。当与我在加拿大（包括北极）操作的其他几台甚高频风廓线雷达相结合时，该系统成为一个强大的国家和国际主要设施，用于研究80至100公里高度的大气过程。拟议的研究计划将利用这种独特的能力。研究将包括对行星波、潮汐波和重力波振荡的风和温度调查、动量通量和散度研究、风强迫、垂直风、湍流强度和微观结构、雷达散射机制、高层大气中二氧化碳增强的影响、流星/空间碎片物理学等。该网络已被用于协助美国宇航局航天飞机重返大气层。在过去的6年里，我发表了46篇论文，我已经证明了我有能力成功地利用这些网络，并期待着充分发挥它们的潜力。
