- 要約等We developed a calibration technique for the MAGDAS/CPMN ground magnetic field data obtained by MAGDAS fluxgate magnetometer, and evaluated the accuracy of the corrected data. The magnetic variations, measured by MAGDAS system, are well correlated with the variation of the sensor-head temperature: so-called temperature drift. A new method was developed to ...... the proportional factor of the temperature drift. It is confirmed that the raw magnetic field data can be corrected by subtracting the temperature drift component, whi......h will be estimated by the derived factor. We evaluated the quantitative validity of the corr...
