在过去五年中，在阐明和描绘地球空间对低层大气非迁移潮汐的响应方面取得了重大进展。卫星飞行任务提供了连续和全球分布的大气参数测量结果，揭示了以前没有预料到的惊人发现。特别强调的是东向传播的周日潮汐与纬向波数3（DE 3），它不仅表现在中性大气中，而且在电离层。DE3潮汐可以从对流层的起源一直追踪到中间层、低热层（MLT）区域的最大值，高度可达400 km。因此，霍夫模式扩展（HME）建模有助于弥合在MLT区域和上层热层进行的卫星测量之间的数据差距。
During the past five years, significant progress has been made in elucidating and delineating the geospace response to nonmigrating tides from the lower atmosphere. Satellite missions providing continuously and globally distributed measurements of the atmospheric parameters revealed astonishing findings not anticipated before. Special emphasis is put on the eastward propagating diurnal tide with zonal wavenumber 3 (DE3) which manifests itself not only in the neutral atmosphere but also in the ionosphere. The DE3 tide can be traced from its origin in the troposphere to its maximum in the mesosphere, lower thermosphere (MLT) region up to an altitude of 400 km. Thereby Hough Mode Extension (HME) modeling aids to bridge the data gap between satellite measurements performed in the MLT region and upper thermosphere.
