摘要
临汾中心地震台地磁FHD观测已有十几年历史,这些观测数据对该区域及全国的地球物理、地震预报等研究起到了重要的作用。通过对临汾中心地震台新地磁房FHD2018年数据完整性分析、常规差分分析、子夜均值对比分析和噪声分析等,得出临汾中心地震台新地磁房FHD完整性一般,数据可用性较好的结论,同时给出一些提高观测质量的建议。
The geomagnetism FHD observations at Linfen Center Seismostation have a history of more than ten years.These observation data have played an important role in the study of Geophysics and earthquake prediction in the region and the whole country. Through the analysis of FHD data integrity,conventional difference,midnight mean contrast and noise in 2018 at Linfen Center Seismostation,this paper draws the conclusion that FHD data integrity is general and data availability is good at New Geomagnetic Room of Linfen Center Seismostation,and gives some suggestions to improve the observational quality.
