CEDAR: The Bear Lake Observatory

研究人员将利用位于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。用法布里-佩罗干涉仪和迈克尔逊干涉仪测量的风、动力和旋转温度以及发射强度将用于研究冬季平流层变暖事件对中纬度地区的影响。这些效应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。这项研究将把全天成像仪对中间层夜光发射的观测与数字电离层探空仪对电子密度的测量结合起来。结果将表明在中间层波活动和电离层状态之间是否存在关系。该项目还包括安装电话线扩展器，以增加电话/调制解调器对天文台仪器的远程访问。

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.
