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年中，已经建造了12个大气/流星雷达的链条，从南极到北极延伸到北美和南美。我是5号的首席研究员，共享第六名，并与其他科学家合作，另外6个。其他人存在于全球。这些雷达都有一个共同的遗产，由我科学设计。它们测量风和温度在80至100公里之间，我仍在开发更多的应用。这种扩展代表了任何单一类型的中间大气雷达的最广泛的纬度覆盖范围和最高的纬度密度。我目前正在将这些设施中的所有数据集成到一个通用网站中，在该网站上，每隔几个小时就会显示和更新所有这些数据，从而促进了雷达所有者与全球其他研究人员之间的互动。该网站以及随之而来的合作科学，代表了中间气氛首次在如此频繁且全球范围内近实时展示通用用户访问的中间气氛。该系统将允许对全球大气动力学研究的独特新观点，在纬度覆盖范围与许多卫星相当，并且在时间覆盖范围和垂直分辨率方面都优于所有卫星。当结合我在加拿大（包括北极）运营的其他几个VHF风能雷达雷达时，该系统为80至100 km海拔的大气过程提供了强大的国家和国际主要设施。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，潮汐和重力波振荡的风和温度研究，动量通量和差异的研究，风力强迫，垂直风，湍流强度和显微镜，雷达散射机制，上层大气中增强的碳二氧化碳的影响，以及我们的高气氛/空间/空间/空间，以及其他物理学等。该网络已被用来协助NASA航天飞机重新进入。在过去的6年中，我有46个被指导的出版物，我证明了自己成功使用这些网络的能力，并期待着发挥其全部潜力。
