Large-scale ionospheric total electron content (TEC) variations have been observed by using a chain of GPS receivers along the east Asia sector ( ˜120° E) and a chain of receivers along the American sector ( ˜70° W) during the October-November 2003 magnetic disturbance period. The day to day Latitude-Time-TEC (LTT) maps constructed from GPS receivers along the same longitudinal line show that the poleward boundaries of the equatorial anomaly in the east Asia can expand to ±30° magnetic latitude on Oct. 29th, followed by severe depletions in next two days. Meanwhile, the LTT maps observed in the American sector show strong equatorial anomaly expansions on both Oct. 29th and Oct. 30th. The poleward boundaries of the anomaly region can expand to ±50° magnetic latitude in this sector. Moreover, during the recovery phase of the storm, a TEC enhancement can be see in both sectors on Nov. 1st. The satellite in situ density and plasma drifts measurements obtained from the Republic of China Satellite-1 (ROCSAT-1) at 600 km height show that the equatorial anomaly expansions are caused by the strong upward plasma drift on Oct. 29th in the east Asia sector and on Oct. 29th and 30th in the American sector. Satellite data also shows that light ions are dominant in some area at night during the storm recovery phase. The component of the plasma drift parallel to the magnetic field measured by ROCSAT-1 is also used to explain this post storm light ion enrichment phenomenon.
