Abstract

Abstract

The conventional diurnal variation correction of multiple geomagnetic stations based on geographic coordinates is to increase the precision of diurnal variation correction by improving the calculation methods. Based on the comparative analysis of conventional diurnal variation correction methods, this study proposed the geomagnetic coordinate fitting method for diurnal variation correction based on the high correlation between geomagnetic coordinates and geomagnetic field strength. The experimental results show that the diurnal variation correction of multiple geomagnetic stations based on geomagnetic coordinates generally improves the precision of diurnal variation correction and, thus, serves as a new study approach for diurnal variation correction of multiple geomagnetic stations.
