CEDAR: Bear Lake Observatory--A Mid-Latitude CEDAR Facility for Middle and Upper Atmosphere Studies

对中高层大气的观测， 在熊湖天文台进行的观测对CEDAR的目标至关重要 研究大气不同区域之间的耦合。 中纬度观测提供了一个非常不同的视角， 与极光带和极冠的耦合相比， 或者在赤道地区。 有两类问题 特别适合在中纬度地区进行研究， 这些都是从BLO追查出来的 最早的研究 磁层影响的大气过程 过程是最小的。 其他研究扩展 磁层影响进入中纬度地区，这可能 发生在极光区向赤道扩张的时候 或者来自向极延伸的环电流效应的增强。

The observations of the middle and upper atmosphere that can be made at Bear Lake Observatory are vital to the CEDAR objectives of studying coupling among different regions of the atmosphere. Mid-latitude observations provide a very different perspective of coupling compared to those made in the auroral zone and polar cap or in the equatorial region. There are two categories of problems that are particularly amenable to study from a mid-latitude site, and these are being pursued from BLO. The first studies atmospheric processes where the influence of magnetospheric processes are minimal. The other studies extensions of magnetospheric influences into the mid-latitude region, which may occur from an expansion of the auroral region towards the equator or from enhancements of ring-current effects extending poleward.
