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.

大学。科罗拉多州的巨石标题：极地层云及其大气环境，极性的层云通过水蒸气凝结到冰颗粒的高度附近，在85公里的高度附近产生。 自1983年以来，NSF支持了NSF的“夜光云”，有时在仲夏中可以看到它们。 该延续建议是研究云特性的季节性，纬度和北/南/南/南/南变异性，与包括成核的微物理学相比。 提出的工作对于扩展我们对极地云层涉及物理的理解以及对夏季极性中层层的垂直和波动运动以及南极和北极中圈之间的差异很重要。 PI和他的同事有资格进行研究，他们与他人的合作将增强结果。
