Radar Studies of the Polar Summer Mesosphere

有各种各样的技术用于研究高层大气的结构和动力学。康奈尔大学开发了一种便携式雷达干涉仪，可以测量大气中层顶区域的大气散射。对这些数据的分析可以得出有关该地区的风、密度和能量损失机制的信息。本文关注的项目是利用相关数据与格陵兰岛Sondestrom峡湾的非相干散射雷达合作，研究夏季极地中间层云。将联合分析挪威EISCAT雷达所获得的类似研究结果，以期充分了解极地中间层云、它们与夜光云的关系以及该区域的动态。来自不同仪器的不同雷达频率的相对响应将有助于对数据的解释。

There are various techniques used to investigate the structure and dynamics of the upper atmosphere. Cornell University has developed a Portable Radar Interferometer that can measure the scattering from the atmosphere in the mesopause region of the atmosphere. Analysis of these data leads to information on winds, densities and energy loss mechanisms in that region. The project of concern here is to take correlative data in collaboration with the incoherent scatter radar in Sondestrom fjord, Greenland to study polar mesospheric clouds during the summer. Similar studies obtained at the EISCAT radar in Norway will be jointly analyzed in an attempt to fully understand the polar mesospheric clouds, their relationship to noctilucent clouds and the dynamics of the region. The relative response of the different radar frequencies from the different instruments will assist in the interpretation of the data.
