CEDAR Postdoc: Observational and Modeling Studies of Dynamical Forcing on Polar Mesospheric Clouds

该奖项是为了支持一名博士后研究极地中间层云(PMC)。这项研究将利用卫星观测和数值模式相结合的方法来研究PMC亮度和出现频率的全球变化，并确定其对瞬变中间层动力学的依赖性。卫星观测来自学生一氧化氮探测器(SNOE)和热层、电离层中间层能量和动力学(TIMED)航天器。组合后的数据集将被用来建立SNOE观测中看到的动力学特征与TIMED测量的温度和水汽的对应特征之间的联系。这些数据将与大气气候模型和云微物理模型相结合，以帮助澄清引起中层大气温度和水蒸气观测变化的动力学过程。

This award is to support a postdoctoral researcher to study polar mesospheric clouds (PMC). The study will make use of a combination of satellite observations and numerical models to study the global variation of PMC brightness and occurrence frequency, and determine the dependence on transient mesospheric dynamics. The satellite observations are from the Student Nitric Oxide Explorer (SNOE) and the Thermosphere, Ionosphere Mesosphere Energetics and Dynamics (TIMED) spacecraft. The combined data sets will be used to establish the connection between dynamical features seen in the SNOE observations and their counterpart in temperature and water vapor measured by TIMED. The data will be combined with an atmospheric climate model and a cloud microphysics model to help clarify the dynamical processes that give rise to observed variability in temperature and water vapor in the middle atmosphere.
