Abstract In this paper, the authors have analyzed and compared the diurnal variation curves in several survey areas, studied the curves and their disturbance features of magnetic diurnal variation in different places, and summarized magnetic diurnal variation curve features of other external disturbance and curvilinear distortion of instrument reasons. Based on comprehensive analysis and research, the authors have summarized the curve features of magnetic disturbance, external disturbance and instrumental interference, and provided the basis for quick identification of magnetic disturbance and correct editing and processing of magnetic diurnal variation data.
