A method for geoelectric counts interference reduction based on extrema ccharacteristic scale

ZHENG Jiang-rong1,XIE Fan2*,ZHANG Xiu-xia1,BAO Hai-ying1(1.Earthquake Administration of Jiangsu Province,Nanjing 210014,China; 2.Institute of Geophysics,CEA,Beijing 100081,China)  
Geomagnetic and geoelectric measurements is carried out at the same time in some stations of the earthquake precursor observation networks of China.Due to this situation,the geomagnetic signals can be interfaced by the geoelectric measurement once an hour.This will make earthquake precursor and other anomalous geophysical information difficult to be distinguished from geomagnetic signals,meanwhile,the observation data quality will declined.The paper firstly analyzes the characteristics and mechanism of this kind of interface,then extrema characteristic scale as well as pre-whitening technology is introduced as the effective methods to geoelectric counts interference identification and reduction.Normal distributed white noise as an assistive technology is added into original geomagnetic data in order to help identify the interface intervals with extrema scale precisely.Then these identified intervals are filled with linear interpolation.Using this method thought stimulated geomagnetic diurnal change data,the max reduction loss is ±0.03nT.This method was applied to data of observation stations of Chengdu(CDP),Mengcheng(MCH),Luoyang(LYA)and Xu Zhuangzi(XZZ).The result shows that this method has a high and stable identification accuracy and minimal reduction error.It's a valuable method in geoelectric counts interference reduction and geomagnetic data accuracy improvement.
