Dynamics & Coupling of the Mesosphere & Lower Thermosphere - Studies with Meteor Radar & EISCAT

中间层和低层热层（MLT）是高度在~ 50 / 110 km的大气部分。该项目将使用一系列复杂的流星雷达、位于斯堪的纳维亚半岛的国际EISCAT雷达、美国国家航空航天局（NASA）的中间层冰航空卫星和三个数值模型来研究MLT的风、潮汐和波浪，并研究它们如何控制极地中间层云。这项工作的一个特别重点将是了解太阳变率如何影响这些高度的大气，并研究耦合过程如何将MLT与底层低层大气和上层大气联系起来

The mesosphere and lower thermosphere (MLT) is that part of the atmosphere at heights of ~ 50 / 110 km. This project will use an array of sophisticated meteor radars, the international EISCAT radar in Scandinavia, the NASA Aeronomy of Ice in the Mesosphere satellite and three numerical models to study the winds, tides and waves of the MLT and to investigate how they control Polar Mesospheric Clouds. A particular focus of the work will be to understand how solar variability influences the atmosphere at these heights and to study how coupling processes connect the MLT to the underlying lower atmosphere and the upper atmosphere above
