摘要
Electrojet Zeeman Imaging Explorer (EZIE)是一项创新的多卫星任务，可以对地球大气层上层流动的强电流的磁指纹进行成像。ezzie对这些电喷流的多点测量将为几十年来争论不休的地球与周围空间相互作用的谜团提供答案。EZIE的三颗卫星中的每一颗都携带一个微波电喷磁图(MEM)仪器，该仪器由四个相同的118 ghz外差偏振光谱仪组成。它们的设计和优化，以经济有效地满足EZIE的测量要求。EZIE的MEM仪器使用塞曼效应来推断海拔约80公里处的磁场。这项技术已被广泛用于推导太阳的磁场。EZIE现在将这种技术应用于地球系统。
Microwave Electrojet Magnetogram (MEM) Instrument for the Electrojet Zeeman Imaging Explorer (EZIE) Mission
The Electrojet Zeeman Imaging Explorer (EZIE) is an innovative multi-satellite mission that images the magnetic fingerprint of intense electrical currents flowing in the upper layers of Earth's atmosphere. EZIE's multi-point measurements of these electrojets will provide closure to decades-old, and much debated, mysteries of the interaction between the Earth and the surrounding space. Each of EZIE's three satellites carries a microwave electrojet magnetogram (MEM) instrument which consists of four identical 118-GHz heterodyne spectropolarimeters. They are designed and optimized to cost-effectively meet EZIE's measurement requirements. EZIE's MEM instruments use the Zeeman effect to infer magnetic fields at ~80 km altitude. The technique has been used extensively to derive the Sun's magnetic field. EZIE now applies this technique to the Earth system.
