This proposal is a continuation request for radar and optical observations of the polar thermosphere and mesosphere which the PI started a few years ago. The research will emphasize studies of changes in thermospheric composition and thermodynamics at various heights between 85 km and 300 km. The changes will result from various solar terrestrial interactions, such as precipitation of auroral particles of different average energies. In particular the PI wants to study the effects of solar magnetic clouds (SMCs) and coronal mass ejections (CMEs) in the height range of 150 - 200 km in the polar environment. The part on gravity waves and tides should be of interest to the scientific community. The science proposed is relevant to both the CEDAR and Space Weather Programs.

该建议是对极地热层和中间层进行雷达和光学观测的延续请求，这是PI几年前开始的。这项研究将着重研究85公里至300公里之间不同高度的热层组成和热力学的变化。 这些变化将是各种日地相互作用的结果，例如不同平均能量的极光粒子的沉淀。 特别是，PI希望研究极地环境中150 - 200公里高度范围内太阳磁云（SMC）和日冕物质抛射（CME）的影响。 关于重力波和潮汐的部分应引起科学界的兴趣。所提出的科学与CEDAR和空间气象方案都有关。
