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将研究中间层云的现象、其大气环境及其在中层大气全球变化中的作用。 PI将结合联合收割机：（1）对航天器、火箭和地面雷达收集的现有数据进行数据分析;（2）对中间层冰粒演变的微观物理学和大气环境进行理论建模，包括中间层和低热层的耦合动力学、辐射和光化学。 这项研究将增进对中上层发生的物理过程的了解，这一大气层区域由于其复杂性和难以进入而仍然知之甚少。
