The investigators will use data from ground-based radio-wave and optical instruments at the Bear Lake Observatory near Logan, Utah, to address two problems in atmospheric sciences. The first is a study stratospheric warming events. Measurements of winds, kinetic and rotational temperatures, and emission intensities made with Fabry-Perot and Michelson interferometers will be used to study mid-latitude effects from wintertime stratospheric warming events. These effects are evidence for dynamic coupling between low and high latitudes. The second task is to study gravity wave coupling between the neutral atmosphere and ionosphere. This study will combine observations of mesospheric nightglow emissions made by the all-sky imager with electron density measurements made by the digital ionosonde. The results will show if there is a relationship between mesospheric wave activity and the state of the ionosphere. The project also includes the installation of a telephone line extender to increase the phone/modem remote access to observatory instruments.

研究人员将利用犹他州洛根附近的熊湖天文台的地面无线电波和光学仪器的数据来解决大气科学中的两个问题。第一个是研究平流层变暖事件。利用法布里-珀罗和迈克尔逊干涉仪测量风、动力和旋转温度以及发射强度，将用于研究冬季平流层升温事件对中纬度的影响。这些影响是低纬度和高纬度之间动态耦合的证据。第二个任务是研究中性大气和电离层之间的重力波耦合。这项研究将把全天空成像仪对中间层夜光发射的联合收割机观测与数字电离层探测仪对电子密度的测量结合起来。结果将显示中间层波活动与电离层状态之间是否存在关系。该项目还包括安装一个电话线路延长器，以增加电话/调制解调器对观测仪器的远程访问。
