CEDAR: Mid-Latitude Long-Term Mesospheric and Lower Thermospheric Dynamics Measurements from a Mid-Latitude Site at Peach Mountain, Michigan

这项提议要求Cedar继续支持密歇根州桃山天文台(PMO)的一套光学仪器的数据操作和分析。该方案将解决以下目标：1)继续收集中层和低热层的地球物理数据(中性风和对应于羟基和原子氧的气辉层温度)，以建立长期的中纬度气候学；2)通过比较FP I、ASI和FTS同时获得的数据集来协调和操作实验；3)对研究生进行光学实验操作方面的培训以及对数据集的解释；4)将收集的地球物理数据集提交给Cedar NCAR数据库；5)结果的分析和发布。特别是，来自PMO的数据将被用来描述中间层和较低热层中的重力波和潮汐行为，以试图确定背景中性风体流在解释重力波波动方面的意义。

This proposal requests continued CEDAR support to operate and analyze data from the set of optical instruments at Peach Mountain Observatory (PMO), Michigan. The program will address the following objectives: 1) the continued collection of mesospheric and lower thermospheric geophysical data (neutral winds and temperatures for airglow layers corresponding to hydroxyl and atomic oxygen) to establish a long-term, mid-latitude climatology; 2) the coordination and operation of experiments through the comparison of data sets acquired simultaneously by the FPI, ASI, and FTS; 3) the training of graduate student in the operation of the optical experiments plus the interpretation of the data sets; 4) the submission of the collected geophysical data sets to the CEDAR NCAR data base; 5) the analysis and publication of results. In particular, data from the PMO will be used to characterize gravity-wave and tidal behavior in the mesosphere and the lower thermosphere in an attempt to determine the significance of the background neutral-wind bulk flow in the interpretation of gravity- wave fluctuations.
