安徽六安磁通门台阵数据质量分析及方法应用

Data Quality Analysis and Method Applications of the Fluxgate Array in Lu'an,Anhui

安徽省地震局于“十三五”时期在皖大别山地区建设由15个台点组成的磁通门台阵,选取2023年6—9月地磁三分量的观测资料,通过该时间段的数据连续率、完整率判断仪器的运行状况,利用数据的拟合分析、地磁加卸载响应比、逐日比和大致处在相同经度、纬度仪器的日变特征分析对仪器运行以来的观测数据质量进行分析评估,得出安徽六安地区磁通门台站数据质量较好结论。

In"the 13th Five-Year Plan"period,the Anhui Earthquake Agency constructed a fluxgate array consisting of 15 stations in the Dabie Mountain area in Anhui Province.This paper selects the three-component observation data of the geomagnetic field from June to September 2023,judges the operation status of the instrument by the continuity and completeness rates of data during the period,analyzes and evaluates the quality of observation data since the operation of the instrument by utilizing the fitting analysis of data,the response ratio and day-by-day ratio of geomagnetic loading and unloading,and the analysis of the daily characteristics of the instrument at the approximate same longitude and latitude,and concludes that the data quality of fluxgate stations in Lu'an,Anhui is better.
