Polar Mesospheric Clouds and their Atmospheric Environment

该项目将研究中间层云现象、它们的大气环境以及它们在中层大气全球变化中的作用。PI将结合(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)建立了中间层冰粒子演化和大气环境的微物理理论模型，包括中间层和低层热层的耦合动力学、辐射和光化学。这项研究将增加对发生在上层中间层的物理过程的了解，由于其复杂性和不可接近性，这一大气区域仍然知之甚少

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.***
