Auroral Electrojet (AE, AL, AO, AU) - A Global Measure of Auroral Zone Magnetic Activity

The AE index is derived from geomagnetic variations in the horizontal component observed at selected (10-13) observatories along the auroral zone in the northern...AE指数（AE index）由沿北极极光带选定的（10至13个）地磁观测站所观测到的水平分量地磁变化推导得出。
