High Latitude Plasma Structures Campaigns During Solar Maximum

高纬度等离子体结构运动（HLPS）旨在了解在高纬度极帽热层中观察到的电离结构的一般形态。所研究的许多不同现象都依赖于太阳活动周期，其中一些关键过程仅在太阳活动极大期才明显。由于未来几年是最大的太阳活动周期之一的高峰期，因此存在一个独特的机会，可以在许多不同的极地位置使用许多不同的诊断仪器进行广泛的协调观测来研究这些现象。这个拟议的项目将使科学家能够充分利用1990年和1991年在格陵兰岛的两个偏远地点最近安装的两个现代数字电离层探空仪（Digisonde）。

The high latitude plasma structure campaigns (HLPS) are aimed at the understanding of the general morphology of ionization structures that are observed in the high latitude polar cap thermosphere. Many of the different phenomena that are studied are solar cycle dependent with some of the key processes apparent only at solar maximum. Since the next few years are at the peak of one of the largest solar activity cycles a unique opportunity exists to study these phenomena with extensive coordinated observations at many different polar locations with many different diagnostic instruments. This proposed project will enable scientists to take full advantage of two recently installed modern digital ionosondes (Digisonde) at two remote locations in Greenland during HLPS campaigns in 1990 and 1991.
