Analysis of the operation quality of FHD-2 proton vector magnetometer in Heilongjiang Province
The quality of the data records of the FHD-2 proton vector magnetometer at Harbin,Wangkui,and Tonghe geomagnetic stations in Heilongjiang Province was evaluated based on the data continuity rate and integrity rate,background noise evaluation,and the spatial correlation analysis indexesof the vertical component diurnal variation.Affected by the development and construction around the station,the quality of geomagnetic observation data is decreasing year by year.Based on the characteristics of the proton magnetometer,the temperature difference analysis of the geomagnetic observation data shows that the quality of the observation data is greatly affected by the seasonal temperature change in the study area.
