This project will design, fabricate, and deploy a longitudinal network of instruments along the magnetic equator in the Indo-Pacific region in order to facilitate investigations of day-to-day low-latitude ionospheric variability, particularly with regard to migrating and non-migrating tidal structures. Such measurements will be able to resolve space-time ambiguities in satellite observations of wave structures, and the project will determine whether such structures are produced as a standing wave pattern or by zonally propagating, non-migrating waves. Specifically, the instrumentation will include magnetometer pairs and radars capable of obtaining both 150 km and equatorial electroject echos. This project will build upon previously established international collaboration and foster new partnerships with international investigators.

该项目将沿着印度洋-太平洋地区的磁赤道设计、制造和部署一个纵向仪器网络，以促进对日常低纬度电离层变化的调查，特别是关于迁移和非迁移潮汐结构的调查。这种测量将能够解决卫星观测波浪结构时的时空模糊性，该项目将确定这种结构是作为驻波模式产生的，还是通过纬向传播的非迁移波产生的。具体来说，仪器将包括磁力计对和能够获得150公里和赤道电射回波的雷达。该项目将以以前建立的国际合作为基础，并促进与国际研究人员建立新的伙伴关系。
