Polar Mesospheric Clouds and Their Atmospheric Environment

大学。科罗拉多州博尔德：极地中间层云及其大气环境极地中间层云是在接近85公里的高度由水蒸气凝结到冰粒上形成的。它们有时在仲夏在高纬度地区可见，因为自1983年以来，美国国家科学基金会一直支持托马斯博士和他的团队从太阳中间层探测器卫星获得的关于这些云的数据分析。这一延续建议是研究云性质的季节、纬度和南北变化，并与包括成核微物理的模型进行比较。拟议的工作对于扩大我们对极地中间层云所涉及的物理、夏季极地中间层的垂直运动和波动以及南极和北极中间层之间的差异的理解是重要的。PI和他的同事很有资格进行这项研究，他们与其他人的合作将提高结果。

Univ. Colorado at Boulder Title: Polar Mesospheric Clouds and Their Atmospheric Environment The polar mesospheric clouds are created at heights near 85km by water vapor condensation onto ice particles. They are sometimes visible in midsummer at high latitudes as "Noctilucent Clouds" NSF has supported since 1983 the analysis of data on these clouds obtained by Dr Thomas and his team from the Solar Mesosphere Explorer satellite. This continuation proposal is to study the seasonal, latitudinal and north/south variability of cloud properties, in comparison with a model which includes the microphysics of nucleation. The proposed work is important for extending our understanding of the physics involved in polar mesospheric clouds, and also of the vertical and wave motions in the summer polar mesospheres, and of the differences between the Antarctic and Arctic mesospheres. The PI and his associates are well qualified to carry out the research, and their collaboration with others will enhance the results.
