| 摘 要： | 对汶川Ms8.0地震前的TEC数据用卡尔曼滤波法进行异常检测，分析了TEC异常的可信性以及地震激发TEC异常的可能机制，确认地震前第3天（5月9日）和第2天（5月10日）的显著TEC异常与地震临近有关，可以作为地震电离层前兆信息之一。

| Abstract: | We have detected the anomalies of ground-based GPS TEC data by using Kalman filtering.We made a concrete discussion of approaches for carrying out Kalman filtering,and practically applied it to an analysis of 2-dimensional TEC data.Considering Solar-Terrestrial environmental factors such as solar activity,magnetic storms and disturbances,we analyzed the TEC anomalies processed with Kalman filtering,discussed the creditability and the exciting mechanism of the anomalies and confirmed that these distinct TEC ... |
