摘要：
As an attempt, the Kalman filter was used to study the anomalous variations of ionospheric Total Electron Content(TEC) before and after Wenchuan Ms8. 0 earthquake, these TEC data were calculated from the GPS data observed by the Crustal Movement Observation Network of China. The result indicates that this method is reasonable and reliable in detecting TEC anomalies associated with large earthquakes.
