During its sixth scientific assembly in Exeter, United Kingdom, the International Association of Geomagnetism and Aeronomy (IAGA) designated September 1991–March 1993 as the International Equatorial Electrojet Year (IEEY). During this period, intensive and coordinated campaigns on the equatorial electrojet (EEJ) and related aeronomic phenomena are being conducted using a variety of observational techniques at low latitudes. IAGA urges all concerned scientific communities to participate actively in this program. The IEEY is an international cooperative project to improve our understanding of the geophysical, aeronomic, electrodynamic, and plasma processes that control the EEJ current, especially its spatial structure, space and time variations, instabilities, and induced effects. It offers interesting opportunities for EEJ study groups around the world to intensify their activities in a coordinated way. Here, we describe the scientific perspectives and goals of the IEEY, which is coordinated by IAGA's Inter-Divisional Commission on Developing Countries.
