This project is to produce a new data set of gravity waves in the upper stratosphere based on Cloud Imaging and Particle Size (CIPS) measurements from the Aeronomy of Ice in the Mesosphere (AIM) satellite. The CIPS data set at ~50 km altitude will provide measurements of gravity waves observed in CIPS measurements of ozone albedo that complement the Atmospheric Infrared Sounder (AIRS) measurements from the Aqua satellite at ~35 km. The postdoctoral fellow will work with CIPS researchers to produce the data set of waves and then work with the AIRS research team to analyze the gravity waves and understand their geophysical significance. The work builds on an ozone retrieval algorithm for CIPS data that was recently developed by the principal investigator (PI) as part of his PhD work. This project will be carried out at Virginia Tech under the mentorship of Dr. Scott Bailey and at NWRA in Boulder, CO under the mentorship of Dr. M. Joan Alexander and with the participation also of Dr. Cora Randall at University of Colorado, who is the PI on the CIPS instrument. The effort will result in a new dataset for gravity waves which covers a segment of the spectrum which isn't presently well constrained by observations. The dataset will be made publicly available so that it can be used by the community to help advance our understanding of gravity waves and their effects on global circulation. The fellowship is crucial to the development of a young researcher who has alreadyshown significant potential through his strong contributions to the AIM mission. The research project coupled with a strong mentorship program as well as teaching and faculty development opportunities will yield a valuable, productive member of the aeronomy community.

该项目的目的是根据中间层冰的高层大气学（AIM）卫星的云成像和颗粒大小（CIPS）测量结果，产生一套新的平流层上部重力波数据。CIPS在约50公里高度的数据集将提供CIPS臭氧层探测器测量中观测到的重力波测量结果，补充Aqua卫星在约35公里高度的大气红外探测器测量结果。博士后研究员将与CIPS研究人员合作产生波的数据集，然后与AIRS研究团队合作分析重力波并了解其地球物理意义。 这项工作建立在CIPS数据的臭氧检索算法的基础上，该算法是首席研究员（PI）最近在其博士工作中开发的。 该项目将在斯科特·贝利博士的指导下在弗吉尼亚理工大学进行，并在科罗拉多州博尔德市的NWRA进行。Joan亚历山大和科罗拉多大学的Cora Randall博士也参与了研究，他是CIPS仪器的PI。这一努力将产生一个新的重力波数据集，它覆盖了目前没有很好地受到观测约束的一段频谱。该数据集将公开提供，以便社区可以使用它来帮助我们加深对重力波及其对全球环流影响的理解。该奖学金对于一位年轻研究人员的发展至关重要，他已经通过对AIM使命的巨大贡献显示出了巨大的潜力。该研究项目加上强大的导师计划以及教学和教师发展机会，将产生一个有价值的，富有成效的高层大气物理学社区成员。
