The PI will study the phenomenon of mesospheric clouds, their atmospheric environment, and their role in middle atmospheric global change. The PI will combine (1) data analysis of existing data gathered by spacecraft, rockets and ground-based radar; and (2) theoretical modeling of the microphysics of mesospheric ice particle evolution, and of the atmospheric environment, including coupled dynamics, radiation, and photochemistry of the mesosphere and lower thermosphere. The research will increase understanding of physical processes occurring in the upper mesosphere, an atmospheric region which is still poorly understood because of its complexity and inaccessibility.***

PI将研究中层云的现象，它们的大气环境以及它们在中大气中的全球变化中的作用。 PI将结合（1）对航天器，火箭和基于地面雷达收集的现有数据的数据分析； （2）中层冰颗粒进化的微物理学以及大气环境的理论建模，包括中层和下热层的耦合动力学，辐射和光化学。 这项研究将增加对上层上层发生的物理过程的理解，这是一个大气区域，由于其复杂性和无法获得性。***
