Global middle atmosphere dynamics using meteor and VHF radar networks

在过去的10年里，已经建造了一个由12个大气/流星雷达组成的链，从南极延伸到北极，穿过北美和南美洲。我是5号卫星的首席研究员，分享6号卫星，并与其他科学家在另外6号卫星上合作。世界各地都有其他科学家。这些雷达都有一个共同的遗产，都是我科学设计的。它们测量80到100公里高度的风和温度，我还在开发更多的应用程序。这一分布代表了任何单一类型的中层大气雷达中最广泛的纬度覆盖和最高的纬度密度。我目前正在将来自这些设施的所有数据整合到一个共同的网站上，所有这些数据每隔几个小时就会在这个网站上展示和更新，以促进雷达所有者和世界各地其他研究人员之间的互动。该网站以及随之而来的协作科学，代表着中层大气气象学首次以如此频繁和世界范围的规模向一般用户近乎实时地展示。该系统将为全球高层大气动力学研究提供独特的新视角，在纬度覆盖方面可与许多卫星相媲美，在时间覆盖和垂直分辨率方面优于所有卫星。当与我在加拿大(包括北极)操作的其他几个甚高频风廓线雷达相结合时，该系统成为研究80至100公里高度大气过程的强大的国家和国际主要设施。拟议的研究计划将利用这一独特的能力。研究将包括行星波、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、湍流强度和微结构、雷达散射机制、高层大气中二氧化碳增加的影响以及流星/空间碎片物理等。该网络已经被用于协助NASA航天飞机重返大气层。在过去的6年里，我有46份被引用的出版物，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。

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.
