摘要
阐述了中国地震局流动地磁团队现在采用的数据处理流程,包括最近台站替代法的日变通化和自然正交分量模型的长期变化改正。并采用该流程对野外地磁测量数据进行了日变通化和长期变化改正,得到岩石圈磁场年度变化数值,残差分析表明误差不大于10 nT,一般在5 nT之内。
This paper presents the data processing flowchart that is used by mobile geomagnehc monitoring team ot China Earthquake Administration. The processing flowchart includes reducing of diurnal variation and secular var- iations to get annual variation of lithospheric magnetic field. The result shows that residual error is less than 10 nT, generally within 5 nT.
