This project is for the study of the temporal and spatial characteristics of naturally occurring electromagnetic emissions in the extremely low frequency (ELF) band of 3-120 Hz. The emphasis is on the waves which are resonances in the earth- ionosphere cavity, popularly known as Schumann resonances. These resonances are primarily excited by lightning. A global network is planned to make observations in the U.S., China, Australia and Brazil. The observations of ELF waves at various locations on the earth are needed to continuously monitor lightning activity. The study will also provide databases to infer electrical conductivity in the D-region of the atmosphere. In order to make comparative study reliable, all stations of the global network will use the same equipment. The instrument uses innovative technology to create "smart" systems for real-time data acquisition. This is one of the very few projects that has global aspects in middle atmospheric research.

该项目是为了研究在3-120赫兹的极低频段内自然发生的电磁辐射的时间和空间特征。重点放在地球-电离层空腔中的波，也就是通常所说的舒曼共振。这些共振主要是由闪电激发的。一个全球网络计划在美国、中国、澳大利亚和巴西进行观测。为了连续监测闪电活动，需要对地球上不同位置的ELF波进行观测。这项研究还将提供数据库，以推断大气D区的电导率。为了使比较研究可靠，全球网络的所有站点都将使用相同的设备。该仪器使用创新技术来创建用于实时数据采集的“智能”系统。这是少数几个在中层大气研究中具有全球性的项目之一。
