| Abstract: | Using stepwise regression analysis methods and baseline value data at Hongshan geomagnetic station, this paper calculates temperature coefficient, sliding coefficient and annual residual mean square deviation of the geomagnetic observation system to study the influence degree of the three coefficients, provide evidence for data quality controlling at Hongshan geomagnetic station and provide help for reasona- ble selection of baseline value. |
